Method for effectively recording surplus boundary area in recordable CD

Abstract

The invention relates to a recording method of leaving boundary area of recordable disc, it includes steps as following: firstly, in recordable disc, appointing the search position of control data area or the former area; secondly, shake servo is in said appointed searching position; thirdly, in said appointed searching position searches whether is there land-based preset pit; fourthly, under condition of that there is land-based preset pit in said appointed searching position, after the address information is interpreted, the land-based preset pit is executed; fifthly, when said recording is started, if the start address of current address and the leaving boundary area is the same, the recording gate which is used to optical record is operated to execute record. The invention can not be effected by labile factor generated by record starting position of leaving boundary area, so the effect of decreasing failure rate can be achieved.

Description

technical field [0001] The present invention relates to a method for effectively recording the remaining border area in a recordable optical disc. In particular, it relates to a sensitive area of ​​a DVD-R / W disc, i.e. the extra border zone (hereinafter referred to as the remaining border zone) when recording, by retrieving and adjusting the recording position and operating the recording gate to perform stable recording, so as to really improve the quality of the disc. A method for effectively recording the remaining border area in a recordable optical disc with a high recognition rate. Background technique [0002] The DVD model is a type of media defined by the DVD Discussion. All discs of the DVD media type have general characteristics. In the case of a simple single-layer type DVD, its physical track structure is similar to that of a CD. That is, it is in a continuous spiral state, and the term called "track" has the same meaning as the term called "pits" from the vie...

AI Technical Summary

Problems solved by technology

Since there is no jitter, there will be problems with the recording failure on the spindle servo or the recording not going well when there is no land pre-pits

In addition, even if it can be recorded, because there is no land pre-pit or unstable jitter on the front part of the remaining border area, as shown in Figure 8, after recording, it is different from the previously recorded 0x30000 address data area. Gaps between headers or lost coding

In this case, the 0x30000 address cannot be read, so that the disc cannot be recognized
