Disk drive unit with a dustproof cap attached to a body module to protect internal components from dust |
摘要 |
In a disk drive unit, a top cover, a front cover and a loading base attached with a body module cooperatively form a substantially closed receiving space for an optical disk. The front cover is provided with a dustproof shutter which closes the foregoing receiving space except upon insertion or ejection of an optical disk cartridge including therein the optical disk. Further, a dustproof cap is attached to the body module so as to cover the underside of the body module where a circuit board is disposed for processing signals relative to an optical head. A hermetically closed space is formed between the underside of the body module and the dustproof cap, in which the circuit board is accommodated.
