APPARATUS AND METHOD FOR GENERATING WRITE PULSE APPROPRIATE FOR VARIOUS OPTICAL RECORDING MEDIA

摘要

PROBLEM TO BE SOLVED: To provide an apparatus and a method for generating a write pulse appropriate for the type and the recording speed of an optical recording medium.

SOLUTION: The apparatus for generating the write pulse includes: a control unit for providing information on the type and the recording speed of the optical recording medium; and a control signal generating unit which determines the type of a multi pulse on the basis of the information on the type and the recording speed of the optical recording medium provided by the control unit, and generates a signal so that the write pulse having the determined type is generated from a light emitting device. The apparatus for generating the write pulse also includes: a control unit which sets the level of the write pulse for the entire interval or for a partial interval of a write mark and/or a write space of the optical recording medium according to the type and the recording speed of the optical recording medium so that the write pulse has the set level; and a control signal generating unit controlled by the control unit to change the level of the write pulse for each interval of the write mark and the write space.
