Problems solved by technology

One of the known solutions is to further compare the write strategy and write power and other information pre-recorded on the disc after identifying the identification code of the disc, so as to confirm the corresponding real write strategy. This approach must consume a large amount of storage space to store the rest of the relevant information, and the discs that can be supported are limited
[0005] In addition, using the built-in writing strategy and obtaining the best writing laser power by the known optimal laser power correction (OPC) procedure often results in the used writing strategy being different due to manufacturing differences of the optical drive. With the best setting, the mark forming effect is likely to be unsatisfactory, and the writing quality is unreliable, resulting in degraded writing performance (degrade)

Embodiment Construction

[0070] The invention can be used to optimize both write strategies. 1 a and FIG. 1 b are schematic diagrams of exemplary write strategies for programming pits, respectively an exemplary castle type write strategy and an exemplary multipulse type write strategy. Referring to Figure 1a, P w Represents the laser power, P OD (overdrive) represents the overdrive value of the short pattern amplification power ratio, S k and E k respectively represent the increasing width of the leading edge of the short pattern and the increasing width of the trailing edge of the short pattern. The short patterns may include patterns of 3T to 5T. In another embodiment, P w ,P OD , S k and E k Used to write long patterns from 5T to 11T, 14T. In this embodiment, the write strategy parameter P w ,P OD , S k and E k Represents a static write policy parameter. Static writing strategy parameters are related to whether the pattern can be formed and the quality of the formation. In addition, ...

Abstract

A system and method for optimizing write strategy parameters are disclosed. A quality index representing a reproduction result corresponding to a write strategy is acquired. One adjustment procedure is determined from multiple adjustment procedures according to the acquired quality index. The determined adjustment procedure is performed to optimize the write strategy. The write strategy comprises multiple write strategy parameters. Each adjustment procedure comprises at least one of the write strategy parameters to be adjusted and the sequence of the adjusted write strategy parameters.

Description

technical field [0001] The invention relates to an optical storage medium burning technology, in particular to a system and method for optimizing writing strategy parameters. Background technique [0002] With the rapidly increasing demand for digital storage and multimedia applications, optical storage devices, such as DVD recorders, have become standard equipment for personal computers. For each optical storage format, there are many manufacturers producing different types of optical discs. In order to obtain the best writing performance and support a wide range of optical discs, the manufacturer of the optical drive will pre-adjust the best writing strategy for the matching optical disc for various optical discs, and then according to its identification code (disc identification) code), store the best writing strategy in the memory device in the optical drive, so that consumers can get good burning quality in the future. [0003] However, many new optical discs are cons...
