Abstract
A method of optimizing a writing condition of an optical recording medium, including writing test pattern data with the writing condition on the optical recording medium, comparing an error pattern binary signal detected by reproducing the written test pattern data with a correct pattern binary signal of the test pattern data, and determining an optimum writing condition of the optical recording medium based on a result of the comparison.
Claims20
A method of optimizing a writing condition of an optical recording medium, comprising:
- writing test pattern data with the writing condition on the optical recording medium;
- comparing an error pattern binary signal detected by reproducing the written test pattern data with a correct pattern binary signal of the test pattern data;
- and
- determining an optimum writing condition of the optical recording medium based on a result of the comparison.
An apparatus to optimize a writing condition of an optical recording medium, the apparatus comprising:
- a reading and/or writing unit to write test pattern data to the optical recording medium with the writing condition and to read the test pattern data from the optical recording medium;
- and
- a control unit to compare an error pattern binary signal detected by a reproduction of the read test pattern data with a correct binary signal and to determine an optimum writing condition of the optical recording medium based on a result of the comparison.
An information storage medium where information about a writing condition adjustment value of the information storage medium is recorded, wherein the information about the writing condition adjustment value comprises at least one of a width of a first writing pulse of a writing improvement pattern, a shift amount of a start point of the first writing pulse, and a width of a final writing pulse.
A method of optimizing a writing condition of an optical recording medium, comprising:
- writing test pattern data according to the writing condition on the optical recording medium;
- comparing an error pattern binary signal detected via a reproduction of the written test pattern data with a correct pattern binary signal of the test pattern data;
- and
- determining that the writing condition is optimized if the error pattern binary signal is the same as the correct pattern binary signal, or changing the writing condition and repeating the writing, the comparing and the determining.
An apparatus to optimize a writing condition of an optical recording medium on which test pattern data has been written in accordance with the writing condition, the apparatus comprising a control unit to compare an error pattern binary signal detected by a reproduction of the test pattern data with a correct binary signal and to determine that the writing condition is optimized if the error pattern binary signal is the same as the correct pattern binary signal, or to change the writing condition and to repeat the writing of the test pattern data, the comparing and the determining.
