Abstract

The CD driver sharing and switching device is used in integrating PC and CD player into one integral household information appliance. The PC and the CD player share one CD driver for the user to switch at will. During switching, no complex switching program is needed, and the PC can be maintained in normal operation state with or without CD driver without dead halt.

Description

technical field [0001] The present invention relates to an optical drive application system, and in particular to an optical drive shared switching device and method and its application system. Background technique [0002] Due to the development of science and technology, information storage media has also made rapid progress. In the past, magnetic storage media can be said to be the most widely used, but now CD-ROM storage media are widely used for reasons of larger capacity and easy storage. Media is usually accompanied by better audio-visual effects, so personal computers equipped with optical drives and CD players to play high-quality images have become indispensable products for information appliances. [0003] However, there is no product that integrates a personal computer and a CD player in the market today, and there is no integration of a personal computer and a CD player to share a CD drive (commonly known as a CD-ROM drive, hereinafter referred to as a CD-ROM dr...
