Back in the 80's we sold a lot of Sony SL 1800's to discos for long term use, before the DJ showed up. Some of the clubs would open in the early after noons for kids getting out of school and would serve soft drinks, and the club assistant manager would load prerecorded Beta Hifi tapes for the kids to dance to. L 500 tapes gave two hours as I remember and there was a longer tape L 750 and L830 that gave over three. The sound quality was much better than a Revox playing at 3 3/4 its. I still have my JVC 9000 series S-VHS to play back video tapes which are up sampled by my MX 151 and with a little added contrast look fairly acceptable on MY 61" Plasma. As far as sound goes its way better than the picture and better than my Nakamichi 582Z and 682 cassette decks. The issue is tape. You just can't go down and buy decent MAxell or Sony Video tape any more in either format. The advantage of tape is over digital its fairly easy to erase the defect and start over again if you make a mistake. Its not always so easy even on rewrite discs. Its easy to make up programs and download to discs on computers, however. Most of the time I just make up a program and either use Apple TV or Airport Express to feed the Stereo system and forget about making discs. I might make a disc for back-up some times to for the cars. I haven't used video tape in 20 years so knowing which ones hold up better would be a guess. I will say recordings made on Maxell R2R, VHS, and Sony Tape for Beta, lasted over 20 years. MY Maxell cassettes are till going strong after 35 to 40 years and I have Maxell metal Cassettes that are new that I use to make tapes for the 2001 Dodge Ram Diesel. Times have changed. I can remember us ordering 1000 cassettes a month in the beginning. We use to order 7" reels of tape from Maxell, Ampex and BASF by the Gross. We were the largest Pioneer Cassette Machine dealer in the Rocky Mountain time Zone. We did a great business with Nakamichi, too. Tape was a big business for us in all formats for tiny audio Micro cassettes to 1 and 2 inch wide 14 inch in diameter R2R Audio tape. We did well with video tape for consumers, too. Radio stations bought cart tapes by the tons. They bought machines to load tape in their old cart tape cartridges. They bought tape in pancake form to fill 7" and 10 1/2 inch reels. We would stack reels at the radio stations to gain more time for doing remotes. Time goes by fast with a 1200 ft roll running at 15 its. Some times an extra 2 or 3 minutes would make a big difference. We never used 1 mil tape until it became back coated because of print thru issues. And the big old Ampexs, 300 series, could stretch tapes of I mil thickness if not adjust properly. 1/2 mil tape was left for consumers with the understanding we would not replace the tape if deformed by a tape machine. Its been fun thinking back about tape, its some thing I haven't done in a while. Ampex sure double crossed us with their Grand Master series. The original audio tape with sticky on it. I can remember us becoming a Scotch audio tape dealer when they Pioneered their 200 series. It gave tape machine any where from 3 to 6db more dynamic range. And Maxell UD gave another 4 or more Db. Plus the Maxell had much better HF properties. I imagine gaining over 10 to 12 Db of Dynamic range do to tape improvements even with old Magnecord and Ampex tubes studio machines. Thats like putting a turbo and fuel injection on your old V8 engine from the 60's or 70's.
I just remembered the Radio Station had one Ampex that was 15/30 IPS and as the head engineer did want me loading reels in the rewind or FF modes I would use the HS ampex to load all the reels at 30 IPS. . He installed a switch on the deck to by pass the shut-off arm circuit so we could dump old tape on 7 inch and 5 inch reels. 10 inch reels we would remove the flanges and cut the tape off with a carpet knife. The HS Ampex could either be 1/4 inch or 1/2 inch depending on which head stack we used. We installed the extra flutter filter and adjustable tape guides ourselves. The 300-4 I used was strictly 1/2 inch, 7 1/2- 15 its. Mine was special as I used AME equalization designed by MR Dolby himself when he worked for Ampex. It was a pre cursor to Dolby professional noise reduction. He and some others I don't remember developed multi channel sound for movie theaters while at Ampex.
I Was so busy at work and having fun I have no conception as to when audio tape started it downward spiral, DAT tape along I there some where and all of a sudden analog tape was gone.
My part of the country is always behind the times. Recessions come later and recoveries come later. We are slow to get new ground breaking technologies and old technologies stay longer. But now that we have an Apple Store and Best Buy is trying to compete things seem to happen faster. And the internet makes a big difference. One reason why we are slow to change is because of our connection with old Mexico and the fact that its 600 miles to a major city, North, West or East. We are a desert island out in the middle of a Big Desert. I know people in Phoenix are going to be offended. But they are no LA/ Denver/Dallas-Fort Worth/ or Houston. And rich folks don't buy stuff here they go to Dallas or LA. Its to cold and polluted to go to Denver. If they are True Texans, they go to Big-D. Dallas or New York.
