Problems solved by technology

[0008] However, when playing a disc, it is not reasonable to apply the CAV playback speed in all of the above cases
First, there may be situations where the disc in use does not need to be played at the highest speed
For example, if it is a game CD or an audio CD, playback at the highest speed may only cause noise problems for the user
Second, when playing at the highest speed for a long time, there may be problems with data extraction

Abstract

A CD play device capable of adjusting play speed of CD is composed of the following parts as the character: a play-mode selection tool for selecting the CD play mode of constant linear velocity and constant angle velocity, a play speed adjusting tool capable of selecting play velocities when selecting said constant linear speed mode, a manual conversion selection tool selecting the CD play velocity by a manual mode and a manual adjusting tool for adjusting the play velocity of the CD.

Description

【Technical field】 [0001] The present invention relates to an invention of an optical disc player for playing an optical disc, more specifically, an invention about a method for manually adjusting the playing speed of an optical disc when playing an optical disc. 【Background technique】 [0002] Optical recording media capable of recording large-capacity data (hereinafter referred to as "discs") have realized the realization of The rapid development of technology. [0003] Furthermore, the above-mentioned optical discs have been developed as storage media that can be more conveniently used by increasing the recording capacity and increasing the recording and playback speed. [0004] Related to it, in order to record data in the optical disc, in order to play the recorded data, the following two modes are applicable to the recording and playback speed: one is the constant angular velocity (Constant Angular Velocity: CAV for short) playback mode, and the other is the constant l...
