Embodiment Construction

[0062] Embodiments of the method for controlling recording and playing of a multi-layer optical disc of the present invention will be described in detail below with reference to the accompanying drawings.

[0063] As shown in Figure 6, the blue-layer optical disc 130 is fixed by the wiring board 120 in the center to form the first and second recording layers; the inner peripheral area is divided into a fastening area and a lead-in area; the center is a data area; the outer circumference is an outer area.

[0064] The lead-in areas of the above-mentioned first recording layer and the second recording layer are composed of the same PIC data area or the PIC data area of ​​each recording layer; each PIC data area includes playback and recording of the first recording layer and the second recording layer The same adjustment data as the optical power. As described above, the following description will be made by taking the case of including playback and recording optical power adjus...

Abstract

A control method for recording and playing of multi-layers of disk includes the following procedures: identify the recording power data of every disk recording layer and store it to memory unit after processing POC; record the recording power data from the N layer of the base and repeat the procedure of recording shifting between the layers. This method makes it available to record in a certain path and play in the same path.

Description

technical field [0001] The invention relates to a method for controlling the recording and playing of a multi-layer optical disc, in particular to a method for controlling the recording and playing of a multi-layer optical disc which enables the multi-layer optical disc to be recorded according to a certain sequence of paths. Background technique [0002] Recently, a new type of high-density re-recordable optical disc capable of recording and storing high-quality video data and high-quality audio data for a long period of time has appeared. Take an example to illustrate, as shown in Figure 1. Since Blu-ray Rewritable Disc (hereinafter referred to as "Blue Layer Disc") that can be rewritable can be quickly standardized, it is expected to develop related products for commercialization. [0003] Introduces products related to Blu-Layer Discs using record playback devices. In the case of using a blue-layer disc, the cross-section can store 25GB of data; in addition, in the cas...
