Abstract
A power saving system for a flexible magnetic disk drive utilizes a power save signal supplied from a host system. When the power save signal indicates that the disk drive is standing by, a power saving circuit holds unpowered desired components of the disk drive such as a disk drive motor circuit, stepper motor circuit, read/write circuit and sensor circuits. The power saving circuit is constructed to permit the transducer to be recalibrated on a reference track on the disk only when the disk drive is turned on, but to inhibit such recalibration when the power save signal indicates the end of standby, thereby avoiding waste of power.
