Information recording method, information recording medium and information recording apparatus
First Claim
Patent Images
1. A recording apparatus for recording information on a recording medium comprising:
- a detector which detects information stored on the recording medium relating to at least one of recording strategy parameters which include a recording power level, time relations between recording pulses, a lookup table for edge shifting values of at least one of a leading and a trailing edge of at least one recording pulse, and adaptive control sets;
said adaptive control sets being set by at least one of a first timing adjuster for changing a rising edge timing of a head pulse and fixing a falling edge timing of said head pulse, a second timing adjuster for changing a rising edge timing and a falling edge timing of said head pulse, a third timing adjuster for changing a rising edge timing of a tail pulse and fixing a falling edge timing of said tail pulse, and a fourth timing adjuster for changing a rising edge timing and a falling edge timing of said tail pulse;
a converter which converts said at least one of said recording strategy parameters detected by said detector to a parameter for at least one of signal processing, a timing pulse, and a current sink;
a first switch which switches between said first timing adjuster and said second timing adjuster; and
a second switch which switches between said third timing adjuster and said fourth timing adjuster.

Abstract
A recording medium for use with an information recording apparatus which has a timing adjusting controller to adjust a timing of a recording pulse having a disk-like substrate. At least one track is provided on the disk-like substrate and a zone is provided which includes the at least one track. The zone stores information relating to a predetermined timing of a pulse for the recording medium which is detected by the apparatus.
