Problems solved by technology

In particular, in CD R, CD-RW, DVD-RW, etc. in which data can be written, as the density of the signal related to the format of the disc increases, the signal related to the format becomes weaker
[0013] Therefore, there arises a problem that if static electricity enters the holder, for example, a user charged with static electricity directly touches a holder such as a disc pickup with a hand, a weak signal about the format is liable to be destroyed

Abstract

A disc transport member whose width for mounting of a disc is smaller than the diameter of the disc is inserted into and removed from a drive main body while being mounted with the disc. A disc protection member is provided, so as to face the disc, on an edge of the disc transport member or a region close thereto on a side where the disc that is mounted on the disc transport member projects.

Description

[0001] This application is a divisional application of the patent application whose application number is 99110918.X and the application date is June 22, 1999. technical field [0002] The present invention relates to a disc drive which is very suitable for use as, for example, a thin and small-sized optical disc drive. More particularly, the present invention relates to a method of inserting or removing a disc-shaped recording medium into or out of a drive body by means of a disc transfer member such as a drawer or a tray. Background technique [0003] Conventionally, in a thin small-sized optical drive that drives an optical disc such as a CD-ROM and is installed in a notebook-sized personal computer or the like, the mainstream type is one in which a drawer or a tray is used to insert or remove the optical disc from the drive body. As shown in Figures 1(A)-1(C), this type of optical disc drive that has been designed and registered (IBM Corporation) is such that its drawer ...
