Abstract: PROBLEM TO BE SOLVED: To make it difficult to manufacture a pirated version of a disk by providing a recording layer by printing even in a recent high recording density disk wherein a pit surface of a substrate is provided on a laser beam incident side surface. SOLUTION: The recording layer by printing is formed by forming a paint of a material having reflectivity in a prescribed pattern onto a transmissible layer formed on a surface opposite to the pit surface of the substrate or directly onto the surface opposite to the pit surface of the substrate. Thereby, it can be avoided that practical use is made difficult as the case a printing recording layer is merely conventionally provided on the rear side of a reflection film, physical transfer of copy right protection information recorded by printing is difficult and manufacture of the pirated version of the disk is made difficult.

Abstract: PROBLEM TO BE SOLVED: To stably record sub-data in a recording device which records sub-data by means of a mark, which is formed on a reflection film by the irradiation of a laser beam with recording power, to an optical disk recording medium to which primary data are recorded by combination of pits and lands. SOLUTION: The waveform of a reproduction signal obtained at a part, in which the mark as the sub-data is inserted, is replaced with a waveform by a set level. By this, the reproduction signal is free from the influence of the irradiation of the laser beam with the recording power at the mark-insertion part, and an error is not generated in a master clock generated in accordance with a reproduction signal. The generation of the error in the master clock is prevented, and accordingly the mark is accurately recorded to the mark-insertion position. COPYRIGHT: (C)2006,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To precisely eliminate the tracking offset and improve the recording and reproducing performance in recording and reproducing a magnetooptical recording medium of a magnetic domain wall movement detection type.
SOLUTION: After a test pattern is recorded on a recording medium in a state in which a prescribed first offset value is set to a tracking error signal, the reproduction of the test pattern is repeated two or more times while changing the offset given to the tracking error signal, and a second offset value at which an optimal quality for the reproduction signal quality of the test pattern is obtained is determined. From the first and second offset values, an optimal offset value for recording and reproducing is determined. For example, the average value of the first and second offset values is determined to be the optimal offset value.

Abstract: PROBLEM TO BE SOLVED: To reduce a data signal from a magneto-optical disk with a high SN ratio, by utilizing a ghost signal obtained by the movement detection of a magnetic wall, while holding reproducing laser power at an optimum level. SOLUTION: Initially, laser power is controlled, so that the time delay of a ghost signal from a data signal becomes constant times (n) the length of a data detection clock. At this time, a laser power control part 30 searches for a clock of a small jitter quantity from among clocks generated on the basis of an RF signal. Then reproducing laser power is adjusted constant times n=5 as long as a clock closest to the phase delay quantity of a ghost generated in the equal temperature are of laser power, in which previously set signal characteristics becomes optimum. At the time, the control part 30 searches a peak of 5T amplitude, in a moving phase difference control pattern.

Abstract: PROBLEM TO BE SOLVED: To provide magneto-optical recording head device, which is capable of enhancing generation efficiency of magnetic field by lessening the cause that a magnetic head core diameter increases. SOLUTION: A suspension 2 consists of a thin leaf spring of metal, disposed with two constitution parts 2a and 2b (which are an upper spring 2a and a lower spring 2b) varying in thickness and/or material in the state of mutually negating the displacing quantity of the magnetic head 4 generating to the changes in the thickness direction of the magnetic head 4. The upper spring 2a and lower spring 2b are varied in the thickness and/or material, in order to vary their spring constants. A fixed load pressure is exerted to the magnetic head 4 via a slider 3. More specifically, the suspension 2 is formed by making a spring constant k2 of the lower spring 2b on a side of a shorter length larger than a spring constant k1 of the upper spring 2a of the side of the longer length.
