A bit of background Re: DAT decks for storing data: There are two proposed standards, 1) DDS being managed by HP and Sony with 10 other licensed member companies and 2) DD being supported by Apple, Hitachi and Toshiba. DDS is basically a streaming standard, while DD has a changable random access mode and higher data intregrity. The DDS people sat their standard is further along in development and much simpler, while the DD people say their standard is much more usefull in the real world. >From elroy!ames!oliveb!amiga!jimm Thu Mar 30 18:40:38 PST 1989 > > > >1) Will the RDAT really catch on?

Ther'll always be tapes. I'm not sure why, but ther'll always be tapes. >2) Can you make a decent backup using consumer components? I'm not entirely certain you can, but the Marketing Director for Archive Corp, a DDS licensee states that the consumer market will ``significantly impact the price of these drives''. Which makes it sound like a computer DAT drive will not be the same as a home deck, but will share a great deal of commonality. Whether one CAN use a home deck as a backup device would be the $64K question. >)2) Math chips > >The ieee libraries should be able to make use of any reasonable chip, even >if it doesn't drop in as a coprocessor. If these things are as fast as they are supposed to be there may not be any time to go through a library :-), sortof. >From elroy!ames!lll-winken!uunet!portal!cup.portal.com!Classic_-_Concepts Thu Mar 30 18:41:20 PST 1989 > >And DATs have been scuttled by nervous North American manufacturers >who are afraid they will be used for piracy. Codswallop. It hasnt even started yet. The Data DAT market is expected to get a boost from the Consumer DAT market and the Data DAT numbers themselves are pretty impressive: from 21,000 units in 1898 to 585,000 units in 1993. Total market revenue is expected toincrease from $30.4 million to $351 million during that same period, according to Freeman Associates, a Santa Barbera market research firm. They estimate that by 1993, the Data DAT market will secure a 16% unit market share of the entire compter tape storage market, estimated at 3.6 million computer tape drives for 1993. >From elroy!ames!mailrus!jarvis.csri.toronto.edu!utgpu!utzoo!dciem!dretor!king > >>1) DAT decks. > >Excellent idea Richard.

They just started selling them here in LA too, I'm not sure if you can get tapes yet, but *I think* you can. Sombody else mentioned that the local radio station probably recorded their own DAT tapes for airplay - I called them and you're right. The bozo DJ's still say: ``this should sound EVEN BETTER that a CD, this is DAT'' however. >BTW. Flame on you Richard for not answering my mail. Didnt receive it. I got some mail from somebody else at DCIEM, so the paths probably work. Dunno what happened.
