Embodiment Construction

[0013] The present invention provides a recording method aimed at optical discs and having optical disc drive (Optical disc drive) buffer processing and optical disc defect management. The recording method according to the present invention accumulates data in a buffer and continuously performs data recording. Further, when the buffer line is about to overflow, the defect management program is performed on the data in the buffer area, thereby effectively reducing the number of times the defect replacement operation interrupts the data recording program.

[0014] In addition, another scope of the present invention is to compress the recorded data in the buffer, so as to improve the utilization rate of the buffer. The recording method according to a specific embodiment of the present invention uses variable length encoding logic (Run-length encoding algorithm) to compress and encode the data in the buffer to obtain extra space for data temporary storage and recording.

Abstract

A recording method of optical disc includes receiving data packet to be recorded and storing received data packet into storage at buffer storage region, recording data packet stored in storage at buffer storage region onto optical disc plate, coding recorded data packet to be data string flow being stored into storage at buffer storage region to replace original data packet for releasing surplus available space of storage.

Description

technical field [0001] The present invention relates to a recording method for an optical disc, and in particular, the present invention relates to a recording method for an optical disc with buffer handling and defect management. Background technique [0002] At present, the standard of the common format of CD-RW, that is, the standard of so-called CD-MRW (CD-Mount Rainier reWritable), is continuously being discussed. In the CD-MRW standard, a recording section of an information storage medium (ie, an optical disc) is divided into a plurality of areas, and each of these areas is provided with an alternate area. Among these areas, the area where the user data is written is called the data area (DA), and the replacement areas are called the spare area (SA). Generally speaking, when an erroneous block (Block) in a DA is to be replaced, the erroneous block is replaced by a corresponding block in the spare area immediately before the data area. This is the defect management me...
