Embodiment Construction

[0044] The different purposes and features of the present invention will be more apparent by describing specific implementation examples of the present invention in conjunction with the accompanying drawings.

[0045] The structure and function of the exemplary embodiment of the present invention will be described below with reference to the drawings. The illustrations and illustrations relate to at least one exemplary embodiment of the present invention, and are not limited to the technical idea, core construction and effect of the present invention.

[0046] The present invention is aimed at the optical disc (for example: CD\DVD RW optical disc) with recording function, before the above-mentioned optical disc is formatted, in each area to be formatted, in the front empty position of its formatting (recording) OPC determines the optimum recording power, and then formats the area with the determined optimum power while tabulating the optimum power value. If OPC is performed in...

Abstract

The invention discloses an optimum record power formation method of rerecording photomedia, which is characterized by the following: setting a unit of CD specific area; formatting the area; affirming the optimum record power; recording and executing the OPC position information; writing the specific mode data to the area; storing the optimum power value and relating OPC position information in the storage area of CD input-output area after finishing the operation of entire disk. If the input of the disc specific position begins to record the recording order of user data, the storage area of CD input-output area will read the optimum power value corresponding to the specific position.

Description

【Technical field】 [0001] The invention relates to a method for generating optimal recording power in an optical recording and playback system and a method for recording using the optimal recording power generated by the method. It is a method of performing optimal power modulation (hereinafter referred to as OPC) while performing background formatting on an optical disc with a re-recording function, without additionally performing optimal power modulation OPC when writing data. 【Background technique】 [0002] The capacity of CD-ROM, which was once all the rage, can no longer meet people's needs, and it has been replaced by DVD. As a brand-new storage medium, it has attracted people's attention day by day. However, the above-mentioned DVD and the above-mentioned CD realize the same principles. That is, like a CD, with a laser, the difference in the amount of reflected light is recognized using the numbers 0 and 1. It's just that DVD digital storage is more subtle. [0003]...
