DISK DRIVE

摘要

A disk drive is provided to uniformly distribute stress caused while being in contact with a disk cartridge, so that the stress can not be concentrated on a certain part, thereby improving durability and realizing a quiet operation by reducing noise. A tray(220) is mounted with a disk cartridge(221), and is installed to enter a main frame(210). A base chassis(240) is supported on a sub frame(230) rotatively installed on the main frame(210). A shutter opening/closing device(250) is installed on one side of the main frame(210), and opens/closes a shutter of the disk cartridge(221) inserted into the main frame(210). The base chassis(240) comprises as follows. A turn table(241) is mounted with the disk cartridge(221) transferred to the inside of the main frame(240). A spindle motor rotates the turn table(241). An optical pickup device(242) slides in radial direction of a disk(D), and records information on the disk(D) or reproduces the recorded information.
