A computer peripheral that can be connected to a host computer receives a power supply from the host computer. The computer peripheral includes: a USB connectorfor connecting the computer peripheral to the host computer; a first circuit (FDD control IC) which directly receives the power supply from the host computer via the USB connectorand a second circuit (spindle motor driver) which receives the power supply from the computer via the first circuit. The first circuit includes a pull-up circuitfor maintaining a higher voltage level than that of the second circuit and a switchfor turning ON/OFF the pull-up circuitThe first circuit stops supplying the power supply from the first circuit to the second circuit via the switchin the case where the first circuit receives a suspend signal from the host computer to become a standby mode.

In an FDD control apparatus for controlling a floppy disk drive for driving a floppy disk loaded in the floppy disk drive, an FDD control part including a floppy disk controller (FDC) is disposed in an FDD side in lieu of a host side (a SET side). The host side (SET side) is loaded with a USB connector connected to the FDD control part. The FDD control part includes a flash ROM for storing a program for adjusting a step timing of a stepping motor.

A disk holding mechanism for use in a disk apparatus includes a disk holder unit (60) for holding a disk (40) inserted into the disk apparatus. The disk holder unit includes a leaf spring (63) which serves as an urging member for urging a substantial center of the disk downwardly from an upper surface of the disk with the disk held in the disk holder unit. The urging member prevents the disk from vibrating within the disk holder unit and restricts vertical movement of the disk itself even if the disk apparatus is subjected to external shake or shock. Thus, it is possible to constantly maintain stable head touch of a magnetic head to a magnetic disk medium (41) of the disk.
