Abstract

A disc drive apparatus includes a main frame having sidewalls and first and second guides disposed on the sidewalls and opposed to each other, a recording medium holder configured to hold a disc recording medium, a medium drive section, and an ascent / descent retaining member which supports the medium drive section and is attached to the main frame for ascent and descent. The retaining member includes a pair of arm portions, a connecting portion which connects respective one-end portions of the arm portions, pivotal portions arranged on the respective other end portions of the arm portions and supported on the sidewalls, and first and second engaging portions disposed on the respective one-end portions of the arm portions for engagement with the first and second guides, respectively. The first guide is formed of a leaf spring and configured to urge the retaining member toward the second guide.

Description

technical field [0001] The present invention relates to a disk drive device for handling information on a disk recording medium. Background technique [0002] In recent years, optical discs have been widely used as disc recording media, including a read-only type represented by DVD-ROM, a record-once type represented by DVD-R, and a rewritable type represented by DVD-RAM and DVR-RW, which can be used in computer , record and playback externally attached memory for video systems, etc. [0003] An optical disc drive device that records and reproduces information to and from an optical disc is provided with a housing having a disc loading slot for loading and unloading a disc into and from the housing and a disc tray. The disc carrier is movable between a pull-out position, in which discs can be loaded and unloaded, and a drive position, in which a disc drawn into the housing can be driven. [0004] Included in the housing is a motor, which supports and rotates a loaded optic...
