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 internal-
ly.
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.
FAbsolute maximum ratings (unless otherwise noted, Ta = 25_C)
FRecommended operating conditions (Ta = 25_C)
