Embodiment Construction

[0025] The invention provides a method and system for background formatting an optical recording medium by an optical recording device. The optical recording medium can be a CD-RW (Compact Disk Re Writable) or a DVD+RW (Digital Versatile Disk ReWritable) optical disc, and the optical recording device can be a corresponding optical disc drive.

[0026] see figure 1 , figure 1 It is a block diagram of the background formatting system 60 of the present invention and an optical disk drive 70 and a host computer 80 applying the present invention. The optical disc drive 70 includes a memory 72 . The memory 72 is a dynamic random access memory (DRAM), which includes a plurality of sequentially numbered memory cells (not shown). The optical disc drive 70 includes an optical head 76 for reading or writing data on an optical disc. The CD player 70 receives a computer command issued by a host computer 80 (host computer), and performs corresponding operations according to the content ...

Abstract

A method and system for performing background formatting on an optical recording medium by an optical recording device. Each damage management area includes a data area and a replacement area, both of which contain a plurality of information packets for recording digital data. Each information packet includes a plurality of data blocks, and each data block is encoded with a corresponding address information to identify the information belonging to each information packet. The method of background formatting is to firstly create a formatting record table for recording whether the information packet in the damage management area has recorded digital data, and store it in the memory of the optical recording device. When a predetermined format procedure is performed on a packet of the optical recording medium, the corresponding record unit of the formatted record table is first checked. If the corresponding recording unit shows that the current information packet does not record any digital data, the formatting procedure is performed; otherwise, the formatting procedure is performed on the next information packet by skipping the current information packet.

Description

field of invention [0001] The invention relates to a background formatting method, in particular to an optical recording medium for background formatting. Background of the invention [0002] It is known that when the optical disc drive performs background formatting on the optical disc, the optical disc drive receives an instruction from a computer host to format the optical disc, and the optical disc drive only performs a necessary preliminary formatting procedure on the optical disc first. (preliminary formatting procedure). This procedure generally firstly formats a main table area (Main Table Area), a pre-gap area (pre-gap) and a general application area (General Application Area) on the disc, and then sends a reply message Notify the host computer that the formatting of the disc has been completed. In this way, the user can read or write data on the optical disc without waiting for the entire optical disc to be formatted. Therefore, the optical disc drive can reach t...
