Abstract
The present invention relates to a method of maintaining an optimal writing power for various recording modes during data recording onto a recording medium. The present method checks a recording speed at a recording position, reads a write strategy set for the checked recording speed, detects a reflected level while recording data with the read write strategy, and changes a level reference for ROPC according to the detected level. Accordingly, a writing power can be kept most optimal even though a recording speed changes during data recording, thereby improving the quality of reproduced signals.
Claims22
A method for writing data optimally onto a recording medium, comprising the steps of:
- (a) checking a recording mode at a recording position;
- and
- (b) determining whether or not to update a reference of a reflected level for Running Optimal Power Control (ROPC) during data recording based on the checked recording mode.
A method for writing data optimally onto a recording medium, comprising the steps of:
- (a) checking a recording mode corresponding to a recording speed chosen by a user;
- and
- (b) determining whether or not to update a reference of a reflected level for ROPC during data recording based on the checked recording mode.
A method for writing data optimally onto a recording medium, comprising the steps of:
- (a) checking a recording speed at a recording position;
- (b) reading a write strategy set for the checked recording speed;
- and
- (c) detecting a reflected level while recording data with the read write strategy, and changing a level reference for ROPC with the detected level.
An apparatus for writing data optimally onto a recording medium, including:
- a microcomputer for checking a recording mode, and
- determining whether or not to update a reference of a reflected level for ROPC during data recording based on the checked recording mode.
The apparatus as claimed in 17, wherein said microcomputer directs a level detector to repeat a process of detecting a reflected level by a writing pulse during data recording, and using an average of the detected levels as a new level reference of ROPC for a speed changed by a predetermined step.
