Abstract

Provided are an apparatus and method of operating a multi-changer of an optical disc player which restricts an initial operation of the multi-changer of the optical disc by referring to a disc chucking and tray open / close states. According to the method, it is determined whether a type of a disc, which is currently mounted in the disc mounting unit, has been determined before, if a tray open or close key is inputted. If it is determined that the type of the disc has not been determined before, the tray is opened or closed. Then, if the tray is closed, the type of the disc is determined after chucking the disc which is currently mounted in the disc mounting unit. According to the method, it is possible to stabilize a player by restricting an initiating operation of the multi-changer of the optical disc, which occurs needlessly due to a tray open / close key, when a disc is not yet chucked.

Description

[0001] This application claims the benefit of Application No. 2002-41583 filed with the Korean Intellectual Property Office on July 16, 2002, the disclosure of which is incorporated herein by reference. technical field [0002] The present invention relates to an apparatus and method for operating a multi-changer of an optical disc player, and more particularly to a method of restricting a multi-changer of an optical disc player by disc clamping and tray open / close states Apparatus and method for operating a multi-disc changer of an optical disc player initiating operation. Background technique [0003] Typically, a disc-to-disc changer uses only the ON / OFF value to perform the function by stopping the spindle motor and activating the servo chip and pickup. [0004] FIG. 1 is a flowchart of a conventional method of operating a multi-disc changer of an optical disc player. This conventional method determines whether the tray open / key is input, and if the tray open / key is inp...
