Overview
Magnetic disk ICs Read / Write amplifier for FDD BH6627FS The BH6627FS is a 4-mode read / zwrite IC designed for floppy disk drives.
This IC has an internal active filter that can be set to any of multiple settings according to transfer rate, and internal switches for density and inner track / outer track.
Write current can be set to any of multiple settings.
FApplications Floppy disk drives (1MB, 1.
6MB and 2MB drives) FFeatures 1) Internal active filter with four settings that can be selected for multiple Q and f0.
2) Time domain filter with internal switch set according to transfer rate.
3) Any of multiple write current settings can be selected, and inner track/outer track switching is done internally.
