The ATARI 1050 Disk Drive is a record/playback device that allows information to be stored and retrieved quickly and accurately. The actual recording is much like a tape recording process and is done on similar material. The data is magnetically recorded on a 5 1/4 inch diameter diskette. Each diskette can store 88K bytes of data in single density mode and 133K bytes in double density however, double density can only be implemented in conjunction with DOS3. The diskette is inserted through a door in the front panel of the drive unit. The 1050 Disk Drive is used with a single ATARI 400, 800 or 1200 Computer with a minimum of 16K of RAM installed.
