OPTICAL INFORMATION RECORDING METHOD, OPTICAL INFORMATION RECORDING DEVICE, AND OPTICAL INFORMATION RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To solve the problem, wherein a teardrop type mark is formed by recording/reproduction at low linear velocity and the front end jitter of a reproduction signal deteriorates since a medium for recording at a plurality of linear velocities is in a configuration suited for it.

SOLUTION: When recording on a medium that can be recorded at a plurality of linear velocities at a low linear velocity, a recording pulse in which the ratio of the recording power at the front end section to the center section is increased as compared with the ratio of recording power for recording at a higher linear velocity is used. When recording on a medium that can be recorded at a plurality of linear velocities at low linear velocity, a mark shape in which a change from the start end to the terminal is small is achieved, thus improving the front end jitter of a reproduction signal.
