M. Hiramatsu et al., LARGE-CAPACITY AND HIGH-SPEED MAGNETIC-FIELD MODULATION RECORDING FOR3.5'' MAGNETOOPTICAL DISK DRIVE, JPN J A P 1, 31(2B), 1992, pp. 635-637
Recording by magnetic field modulation overwriting with a flying magne
tic head and adopting a 1-7 RLL code, mark-edge recording, and ZCAV fo
rmat, was attempted. A 3.5" magneto-optical disk drive with a large st
orage capacity of greater than 300 MBytes and a high data transfer rat
e of 2.7 MBytes/s on the outermost track was realized.
