Abstract

The invention provides a method to store corrected data to circuit plate and CD machine to realize this method. The CD machine is used to access a CD, and comprises an optical / mechanical assembly (OMA) and e-record element on the OMA stored optical characteristics calibration data of OMA.

Description

technical field [0001] The present invention relates to an optical disc player, and in particular relates to an optical disc player used in a digital versatile disc recording player (DVD-R / RW). Background technique [0002] Many models of digital versatile disc players (Digital Versatile DiscPlayer, DVD Player) that are currently popular on the market have gradually provided the function of burning discs. Disc players are generally referred to as digital versatile disc recorders (DVD-R / RW). [0003] The optical disc player with the function of reading and burning optical discs is the heart of the digital versatile disc recording player. The optical disk drive includes two parts: an Optical / Mechanical Assembly (OMA) and a control circuit board. In order to ensure the quality of CD burning, when burning CDs of different brands and qualities, usually, a set of The optical read-write head, the power calibration data of the emitted laser beam (calibration data of laser power)....
