Magnetic disk ICs Read / Write amplifier for FDD BH6629BFS The BH6629BFS, a read / write IC designed for floppy disk drives, has a recording system that puts top priority on saddle margin. Offers multi-step switching of write current, while density and inner track / outer track edge are switched internally. FApplications Floppy disk drives (1MB and 2MB drives) FFeatures 1) Internal active filter switch. 2) Time domain filter (with internal switching based on transfer rate). 3) Internal switching of write current density and inner track / outer track.
