However, a similar routine must be performed, and if the time interval analyzer or the jitter meter is simply coupled for measurement purposes without an additional control system, the manual adjustment procedure results in The same disadvantages of
In addition, the meaning of the information obtained from that particular instrument is usually implicit, so even an experienced engineer or researcher would spend a lot of time deciding on a new set of write strategy parameters based on it

Embodiment Construction

[0047] The present invention provides a method and system for tuning write strategy parameters of an optical storage device by utilizing data-to-clock edge deviation. According to a first aspect, one of these systems may be a circuit for adjusting write strategy parameters, wherein the circuit is located in the optical storage device. According to the second aspect, one of these systems can also be substantially the optical storage device itself. For the sake of brevity, this first viewpoint is adopted in the following description. However, other implementations (for example implemented according to this second aspect) are also applicable to these detailed examples.

[0048] Please refer to figure 1 , figure 1 It is a schematic diagram of a system 100C for adjusting multiple write strategy parameters (write strategy parameters) of an optical storage device 100 according to a first embodiment of the present invention, wherein the system 100C is a system placed in the optical...

Abstract

A method for tuning a plurality of write strategy parameters of an optical storage device using data-to-clock edge deviations includes detecting a plurality of patterns. Each pattern corresponds to a pit or a land on a phase-changed type optical storage medium accessed by the optical storage device. The method further includes performing calculations corresponding to a plurality of data types and generating a plurality of data-to-clock edge deviations respectively corresponding to the data types. Each pattern belongs to a data type. The data-to-clock edge deviations are utilized for tuning the write strategy parameters corresponding to the data types respectively.

Description

technical field [0001] The present invention relates to write strategy tuning (write strategy tuning) of an optical storage device, especially refers to tuning (tuning) write strategy parameters by utilizing (utilizing) data-to-clock edge deviation (data-to-clock edge deviation) methods and systems. Background technique [0002] As multimedia applications continue to grow, the need to store large amounts of digital data is growing rapidly. Therefore, optical storage media with high storage capacity and small size, such as compact disc (Compact Disc, CD) or digital versatile disc (Digital Versatile Disc, DVD), are very popular, and optical storage devices, such as: CD drive (CD drive) ) or a digital multipurpose optical drive (DVD drive), has become a standard configuration of a personal computer for the above-mentioned multimedia applications. [0003] Taking the above optical drive as an example, when the optical drive is controlled to write data into a rewritable optical...
