Message-ID: <266@nmtvax.UUCP> Date: Tue, 24-Apr-84 02:30:46 EST Article-I.D.: nmtvax.266 Posted: Tue Apr 24 02:30:46 1984 Date-Received: Fri, 27-Apr-84 00:16:05 EST Organization: New Mexico Tech, Socorro, N.M. Lines: 39 Well, this weeks issue of Electronics (April 19th) has a interesting article in it on the idea of using CD digital laser disks a very high density ROMs. They claim that a single CD would have the storage space of half a gegabyte! But until now manufacturing such disks has been expensive. Not anymore. A company (see article) has announced it has a way of stamping CDs like records at a very fast rate. They claim that in volume they could produce CDs for less than the cost of a good floopy diskette. This doesn't count a original $2500 master charge. Compare that to the method of copying software to floppies at the slow rates that must be used. As for cost and speed, lets see. Audio samples at around 44khz with about 16bits per and two channels (stereo) that comes out to about 176k bytes a second or 1.408megabits a second. Not as fast as a hard disk, but what 4in hard disk has that kind of storage? Cost, well a CD player can be found for about $600 these days. Remember that a player for stereo has lots of extra circuitry for conversion to audio that wouldn't be needed for a computer interface. Lets say about $500 including a controller. Not bad! Now who would use such a thing? Well, rumor has it that IBM (yes big blue!) has just purchased over 1.3million of the things. Rumor has it that they may soon unvail a new high density storage system for there computers that will include a CD(s?) with lots of software on it! The reason for this is that IBM wants to blow the competition out of space and time itself. Just imagine what a inexpensive CD with half a meg of software on it would be like if it were inexpensive....why the entire UNIX operating system including sources and all the extras anyone would want would fit with space to spare. Why? Just remember that AT&T has just recently declared war on the market place with its own dreams of creaming the competition. IBM might lose in software costs, but in the long run who would be the loser? Well net landers, what do you think? Can anyone out there imagine writing a software package to be sold on such a thing (i mean half a gegabyte is big!). And remember to that a CD will never wear out. No contact with the playing surface. It may only be readable, but with all that stuff just sitting at your computers fingers tips..... Tim Tucker ...ucbvax!unmvax!nmtvax!tim P.S. Please, no replys of software piracy or theft of CDs. Gag me... P.P.S Remember, you heard it hear first.
