ABSTRACT:
A high capacity computer disk drive system operating a micro-hard disk drive is disclosed in which the hard disk rotates at a speed of approximately 2746 r.p.m. and in which the data received from the host computer for storage on the hard disk is converted to 2,7 RLL coding prior to being written onto the disk. The disk drive system disclosed herein has a formatted data storage capacity in excess of 10 MB and an unformatted digital information storage capacity in excess of 12.5 MB, using both sides of the disk. The micro-hard disk drive system is connected to a host computer using a Small Computer Systems Interface (SCSI) which eliminates the need to provide additional disk controller hardware and software in the host computer. The micro-Winchester disk drive system is particularly suited to meet the needs of a portable computer system.
