Abstract

A disk drive 70 is provided with: a disk drive main body 1; a tray 5 which is openable or closable with respect to the disk drive main body; and a disk mounting section 50 which is provided on the tray to mount a disk. When a disk is located inside walls 55 that form the disk mounting section and the disk is rotated, air flow is generated in the disk mounting section. An escape port 5e is provided on the walls that form the tray to pass the air flow from the inside of the walls to the outside of the walls, and ejection ports 11 and 12 are provided on the disk drive main body to eject air in the disk drive main body. The escape port is provided at a position where an air flow is formed from the front side of the tray to the back side of the tray. The ejection port 11 is arranged at the back side of the disk drive main body. The disk drive main body having the tray can be mounted on a thin notebook type computer.

Description

technical field [0001] The present invention relates to an optical disc player in which, along with the rotation of the optical disc, the heat release of electric / electronic parts such as a substrate, a pickup, etc. is promoted to be cooled. Background technique [0002] An optical disc player that uses a light beam such as a laser to perform a signal reading operation or the like is widespread. The optical disc used in the optical disc drive is, for example, CD (compact disc) or DVD (digital versatile disc / digital video disc). "CD" is an abbreviation for "compact disc". In addition, "DVD" is an abbreviation for "digital versatile disc", or "digital video disc". [0003] As optical discs such as CDs and DVDs, for example, read-only optical discs such as CD-ROM and DVD-ROM, write-once discs such as CD-R and DVD±R, CD-RW, DVD±RW, DVD- Various optical discs such as a writeable / deletable / rewritable optical disc such as a RAM. These optical discs form a medium in which proces...
