Very interesting video, I owned a Sony Betamax many years ago, the problem was on rewind, and fast forward the tape was permanently engaged on the head roller etc, Sony designed their recorders like this causing tape damage, VHS always disengaged the tape, I was pleased to put the Sony in the skip in the end ( comment from England) ps I know Sanyo Betamax would disengage from head but i changed over to vhs by then, and so did Sony

Great one Dave! I wonder: can this shiny upper drum be ONE of the reasons my SL-C7 is having a VERY hard time rewinding?

On my deck, the upper and lower drum looks like what you polished away. Many thanks, Moshe.

Beta always did give a better picture than VHS and that was because the Head drum was larger which resulted in a faster relative tape to head speed. Just like with audio tape running the tape at a faster speed results in better sound same goes for video. The larger the drum the higher the frequency that can be recorded the better the image. Now 8 mm used a smaller drum but had a better picture still that was achieved because 8 mm used metal tape which of course can record a much higher frequency at lower head to tape speed.

I really appreciated the explanation of how a Drop Out compensator worked. The Sony stories are also golden. I do wonder if the shiney surface is a deposition problem from the tape oxide or tape binder to produces a smooth reflective surface, or an actual polishing of the metal. It seems cleaner abrasion wouldn't be hard enough to score the surface.

Video tape is made from colbalt and iron oxide. Both harder than aluminum . The high grade and ultra high grade tapes were worse. The tape was much smoother and it would polish up the drum in a few months. I had a customer that was really anal about using ultra-high grade tapes as he "could see" the difference. He would bring this machine in about every 8 months with complaints that the rewind was getting slow and I would remove the drum take the shine off it put it back in charge of 75 bucks. He would bitch and complain about the cost and I would tell him years regular tape. he would say regular tape didn't give good enough picture and I would say great see you in 6 - 8 months. I probably did this on this machine five times and then he insisted that I wasn't fixing it right and that he wanted the part replaced so I replaced the drum and 6 months later he was back with the new drum in exactly the same situation. I wanted to play the portion of that tape that I have of the Sony training seminar were the instructor discuss the problem of the high grade tape but obviously I couldn't because that would be Sony admitting liability for damaging their own machines. I remember even telling the guy it was his high-grade tapes that was causing it and he went to Sony to complain and I got a call from the Sony service manager telling me you can't tell people that it's the tape that's doing it because of course customers are looking for compensation so we kept that one quiet right up until after the beta was long gone.

The used BASF tape exclusively because the claims of a better picture and longer life. Well it certainly didn't result in longer life for their VCR. I changed the heads twice under warranty wore out 6 months again at 11. Of course they blamed Panasonic because they're old machine which was a Hitachi this never happened on. But yep Panasonic had relatively soft heads. This is how their machines edged out the competition as far as picture quality went. Hard ferrite heads are not very good electromagnetically. Other materials such as permalay are much better, the problem being is that they don't last as long and when you run what amounts to a file through the machine they were out even that much quicker. Out of all the machines I serviced I changed more heads on Panasonic branded machines than anyone else.

The head drums usually got grooves on (on the rotating part). They are to get a thin layer of air under the tape for lubricating it. Same kinda stuff as that with HDD heads. The grooves tend to get filled up with residues over time. Lack of air lubrication can damage the tape, especially while paused (and stepping frames) during play, presumably by friction heat. Personal experience. Sadly I didn't know anything about that at that time. Interesting to see the head switchover artifact put to a diagnostic use. Aah, the noisy ice cream guy van. Haha!

So basically these heads are exclusive for video and none of them for audio right?, if so where the audio hifi heads are located?. Thanks.

@12voltvids

3 жыл бұрын

Beta hifi audio is recorded by the same heads that record the video signal. On the beta tape there's enough bandwidth that there what's room to insert the four FM audio carriers between the chroma down converted signal and the luminance FM carrier. They did this by shifting the luminous carrier up by 400 kilohertz. This created enough space between the chroma and the lower side band of the luminance carrier to insert the four audio carriers. For carriers you say but there's only two channels, correct but there's also two heads. To avoid interference from crosstalk they put left and right Channel on separate frequencies for the two heads and there are essentially FM receivers that tune these carriers in and demodulate them and then they are switched rapidly for one head to the other. For my understanding on pal and secam, because the rotational speed of the Head drum is slower there was not enough bandwidth and they had to use an extra set of audio FM heads on a reverse azimuth just like they did with VHS which uses two additional heads and what they refer to as deep layer recording where they record the audio signal at completely different azimuth or angle onto the tape at a strong level and then record the video over top of the audio the video will erase a good portion but not all of the audio signal and because it's recorded at a different angle it's able to be detected. 8 mm and high eight record their audio exactly the same way that beta hi-fi did using the same heads that were used to record the video and this is possible because of the extra bandwidth available.

Buneas I have a question that I would like to ask you. I have an old vhs that when I put on the tape it tries to catch it but it can't, it gets stuck and doesn't get to pick it up to play it, and it costs me to eject it.

As to the Sanyo, some unloaded like VHS, older ones kept the tape threaded. Vcr9100 for example. The downside to all that threading and unthreading is tape damage.

I thought the Betamax PCM audio was similar to the FM modulated VHS HiFi tracks, and not a "true" digital PCM audio encoding scheme. I know there was an external digital audio device that sony sold (can't remember the model number) that would save the digital audio as a black and white video signal on the SuperBetamax machines. We use to use it with a BetaCam SP; it made really wonderful multitrack PCM digital audio recordings.

@12voltvids

3 жыл бұрын

Beta hi-fi is AFM or audio FM modulated similar to VHS hi-fi except it's recorded by the same heads along with the video just on a different frequency. PCM is totally different and uses a PCM adapter which takes the audio signal and turns it into a 44.1 or 48 or 32 kilohertz digital audio signal which is encoded as a standard video frame and recorded by the luminance circuit on a VCR. When you play back the tape it will look like static on your TV screen the PCM adapter was connected to the video in and video out jacks on the back of the VCR. In order for it to operate the built-in dropout compensator needed to be disabled because repeating a deadline with the line above it from video would result in corrupted data. Since the digital audio stream already had CRC data Incorporated any dropouts or loss of data would be reconstructed by the PCM processor. PCM processors were very popular in recording studios prior to the development of digital audio tape. They were used on three quarter inch umatic, as well as betamax machines as full digital audio recorders.

@12voltvids

It's not the upper drum that is the issue. It is the rotating disk that picks up the random noise. Most machines use an external ground that touches the rotating shaft on the bottom or on the top side of the head drum. Sony used the bottom ground electrode on many of their drums but this specific one they went to internal grounding and it's done in the bearings under the rotor inside the lower drum they rely on the actual ball bearing itself to ground the head disc when the bearing starts to wear the grounding is no longer perfect and when the bond is broken you get random noise and the only way to solve that problem is to change the lower drum. I guess if you could find the bearing you could pop the bearing in and that would fix it but the problem is these machines haven't been made for like 30 plus years so the chances of finding a lower drum or the bearing for one of these machines is like finding a needle in a haystack.

Still have the PC based controller I made, that replaced the Frankenstein somebody made for it, you really cannot do long delays with 555 timers and electrolytic capacitors, especially if you want to cascade the timers to so a sequence, and your capacitors are leaky. Made entirely from old repurposed PC's that were scrapped and no longer usable, with 386SX processor on the board. Gave so much better control, and added so many extra functions as well to the basic duplicator function, so I could do basically 8 cycles in a 24 hour period to make copies. Spot QC of one tape from each machine though the day, and the tapes were marked with a small colour dot to indicate machine, and also had a simple date code label on them as well for production. Used to order blank tapes in boxes of 100, 20 boxes at a time, and huge boxes of PVC clamshell covers, as there were both tape labels and inlays for each unit. Pretty much died fast after DVD took off, by 2010 sales were zero, and the lot was placed in boxes.

NV-G70... Now that's a D1 or a G deck? I recently found an NV-G7 in the garbage and the head drum has lots of corrosion.

Have to be careful on facebook including facebook messenger. I was chatting the other day with whom I thought was a former co-worker until it got to the part where he brought up that he had won $300,000 from some government fund and he "saw my name" on some list to get it. Yeah, sure, okay, whatever. Yes the guys account was hacked. You know the old saying if something sounds too good to be true, then it probably is.

That's why I am not active and how everyone knew it was a fake because I am not on Facebook or Instragram or messenger. I use bbme which is enterprise grade security with the few i chat with.

My mom is having the same problem. Someone is using her Facebook information to create fake Instagram accounts.

I'm not on Instragram either.

Sounds more like a bad drum

The bearing is starting to chirp. That is why the sparkles at random. I'm going to run it for awhile as quite often that will work the bearing. The drum speeding up and slowing down on rewind is due to no incoming signal for it to lock to. Put a video signal in and it locks up and stays stable. They are all like that.

This is sooo ugly, but I at least would give it some effort for being HIFI. You have far more patience than I would. Betas are (in my opinion) about 10-15% more mechanically involved in the play mechanism than VHS. I'd rather work on a HIFI / stereo linear audio VHS (both in one) VCR than this. Hope you get fully compensated for this because you deserve it.
