Abstract

PROBLEM TO BE SOLVED: To perform a cleaning operation safely and efficiently without imposing stress on an objective lens, when the objective lens of an optical pickup device is cleaned, and to efficiently use a cleaning disk recording medium. SOLUTION: A cleaning member 9 is disposed on the outer periphery part of the cleaning disk 1 as much as possible, in order to solve the problem in cleaning the objective lens 12 of an optical pickup device. In addition, it is constructed so that the cleaning member 9 is not brought into contact with the objective lens 12 of the optical pickup device at all, at the time of reproducing a program for a purpose other than the cleaning. Accordingly, a disk recording medium is used efficiently and the problem in the cleaning is solved.

However, the disc-shaped recording medium (in the case of a disc having a diameter of 120 mm) has an information recording system in which the linear velocity is constant, so that the rotation speed is set at the innermost portion (diameter of 50 mm). When there is an objective lens of the optical pickup device, the rotation is about 600 revolutions per minute,
6 mm) is about 200 rotations. In other words, the rotational speed of the disk is high at the inner periphery and low at the outer periphery.
Under such conditions, if the cleaning member is provided near the TOC area or near the inner periphery of the program area as in the related art, the optical pickup is physically viewed more than when the cleaning member is on the outer periphery. The impact when the objective lens of the device and the cleaning member come into contact with each other is large, and repeated use gives excessive stress to the objective lens and the mechanism of the optical pickup device, and eventually causes fatal damage. . In other words, in the conventional cleaner, even when a program other than the purpose of cleaning is reproduced, the objective lens of the optical pickup device and the cleaning member unnecessarily come into contact with each other, and the objective lens of the optical pickup device and the mechanism of the mechanism unit are unnecessarily contacted. The service life will be shortened.
