Abstract
An optical disk recording method, and an optical disk recording device to perform the method, the method including generating an over speed write pulse string so that a data recording operation on an optical disk is performed at a record speed exceeding an allowable record speed of the optical disk, and recording data on the optical disk using the generated over speed write pulse string.
Claims37
An optical disk recording device, comprising:
- an optical pickup unit to be driven by an applied write pulse string to record data on an optical disk;
- and
- an optical pickup driving unit to generate and apply an over speed write pulse string to the optical pickup unit so that the optical pickup unit records the data on the optical disk at a record speed exceeding an allowable record speed of the optical disk.
An optical disk recording method, the method comprising:
- generating an over speed write pulse string so that a data recording operation on an optical disk is performed at a record speed exceeding an allowable record speed of the optical disk;
- and
- recording data on the optical disk using the generated over speed write pulse string.
A method of recording data on an optical disk, the method comprising:
- increasing pulse widths of write pulses of an allowable speed write pulse string;
- wherein an over speed write pulse string is formed so that the data is recorded on the optical disk at a record speed exceeding an allowable record speed of the optical disk.
A method of recording data on an optical disk, the method comprising:
- decreasing intervals between write pulses of an allowable speed write pulse string;
- wherein an over speed write pulse string is formed so that the data is recorded on the optical disk at a record speed exceeding an allowable record speed of the optical disk.
