Abstract
A method of optimizing a write pulse string, and an optical disk device to perform the method, the method including measuring an energy level of the write pulse string used in recording data on an optical disk, and controlling a generation of the write pulse string so that the energy level is within a predetermined range above or below a reference energy level.
Claims20
An optical disk device, comprising:
- an optical pickup unit to be driven by a supplied write pulse string to record data on an optical disk;
- an optical pickup driving unit to generate and supply the write pulse string to the optical pickup unit;
- an energy level calculator to calculate an energy level of the write pulse string generated by the optical pickup driving unit;
- and
- a controller to control the generation of the write pulse string of the optical pickup driving unit, so that the calculated energy level is proximate to a predetermined reference energy level.
