Abstract
An optical disk drive, and a method of determining a write strategy thereof. In the method of determining a write strategy of an optical disk drive where a mark and a space are formed on an optical disk by a laser beam to display write information and information is written or reproduced, write quality is evaluated by combining at least two of power- and pulse-based parameters defining a writing multi pulse, and the at least two parameters are changed on a 2-dimensional matrix. The power- and pulse-based parameters indicating specific write quality are determined as strategy parameters, based on evaluated results of the write quality.

A method of determining a write strategy of an optical disk drive in which a mark and a space are formed on an optical disk by a laser beam to display write information and information is written or reproduced, the method comprising:
- evaluating write quality by combining at least two of power- and pulse-based parameters defining a writing multi pulse, and changing the at least two parameters on a 2-dimensional matrix;
- and
- determining the power- and pulse-based parameters indicating a specific write quality as strategy parameters, based on evaluated results of the write quality.
An optical disk drive in which a mark and a space are formed on an optical disk by a laser beam to display write information and information is written or reproduced, the optical disk drive comprising:
- a write strategy operation control unit configured to write quality by combining at least two of power- and pulse-based parameters defining a writing multi pulse and changing the at least two parameters on a 2-dimensional matrix, and configured to determine the power- and pulse-based parameters indicating a specific write quality as strategy parameters, based on evaluated results of the write quality;
- and
- a write pulse adjustment unit configured to generate and output a write pulse train by referring to the determined strategy parameter.
A method of determining a write strategy of an optical disk drive, the method comprising:
- setting a write quality by changing values of at least two arbitrary parameters among power- and pulse-based strategy based parameters into a 2-dimensional matrix;
- and
- determining optimal values of the power- and pulse-based strategy parameters indicating a specific write quality as strategy parameters, based on the set results of the write quality.
