Abstract: The present invention provides an optical disk 9 with a duplication preventing function, reproducing system 47 for the optical disk 9, optical disk reproducing method, method of fabricating an optical disk original record, and illegal program operation stopping method. An area in which a CP signal 24 is recorded is made after a signal having a constant pattern in the optical disk, the CP signal 24 being produced such that the center of an eye pattern is shifted from the center of the amplitude. In the reproducing system, CP signal arrangement information 25 or a CP preceding signal 26 is detected, before an offset voltage is applied to a threshold value to be used in demodulating an RF signal into a digital signal so that the threshold value varies, thus normally reproducing the signal in which center of the eye patter is shifted from the center of the amplitude. The reproducing system has a function whereby the reproduction is stopped when a predetermined offset signal is not reproduced.

Abstract: An optical disk physical has a recording region divided into zones, each zone including physical tracks adjacent to each other. An integer number of sectors are provided in each physical track. The angular recording density is higher in the more outward zones such that the linear recording density is substantially constant throughout the recording region, and logical tracks are formed of a predetermined number of sectors, independent of the physical tracks. The conversion between the logical track and sector addresses read from the disk and the linear logical addresses supplied from a host device is easy. The addresses written in headers of the sectors in the logical track in which data are actually recorded, including substitute sectors used in place of defect sectors, are preferably consecutive to further facilitate the conversion between the logical track and sector addresses read from the disk and the linear logical addresses supplied from the host device. Each of the zones can be set to serve as any of the different types of recording area, independently of other zones.

Abstract: An optical disk storing write-once information usable for protecting the copyright of the software by preventing the duplication, unauthorized use, etc., of the software. In the optical disk, a recording layer (213) is formed on a disk substrate (211) with a dielectric layer (212) inbetween. Then, an intermediate dielectric layer (214) and a reflecting layer (215) are successively laminated upon the recording layer (213), and an overcoat layer (216) is formed on the surface of the reflecting layer (215). A plurality of BCA (one of write-once identification information systems) sections (220a and 220b) are recorded by lowering the vertical magnetic anisotropy of the recording layer (213). At the time of reproduction, the write-once information is detected from differential signals.

Abstract: A disc apparatus (10) includes an optical lens (14). A laser beam is irradiated onto a recording surface of the magneto-optical disc (68) through the optical lens (14), and a TE signal or an RF signal is detected on the basis of the laser beam reflected by the recording surface. Herein, an MPU (50) replaces the optical lens (14) in an optical axis direction, and a TE signal detection circuit (42) or an RF signal detection circuit (60) detects the TE signal or the RF signal at each of lens positions. A laser power is adjusted by the MPU (50) such that amplitude of each of the TE signal or the RF signal detected is below a saturation value. When a parameter is adjusted, a position of the optical lens (14) is controlled such that the amplitude of the TE signal or the RF signal detected thereafter is maximized.

Abstract: The present invention relates to a reading method and apparatus for reading a magneto-optical recording medium comprising at least one storage layer and a read-out layer, wherein an expanded domain leading to a read-out pulse is generated in the read-out layer by copying of a mark region from the at least one storage layer to the read-out layer through heating by a radiation power and with the help of an external magnetic field. A parameter indicating the presence or strength of a local deviation in the read-out characteristic of the recording medium is determined during a reading operation, and the radiation power is then controlled on the basis of on the determined parameter. The proposed procedure can be used during a read-out operation based on a reflected power, read-out error, or phase error. Hence, a fast and efficient power control mechanism that can be independent of a copy window control mechanism is provided. Moreover, crosstalk between first and second storage layers can be prevented by keeping the read-out temperature close to the compensation temperature of the other storage layer which is not read.

Abstract: A disk recording-playback device including a laser drive circuit for feeding a drive signal to an optical head and adjusting the power of a laser beam irradiated by the optical head, an error correcting circuit for detecting an error rate of a reproduced signal, and a system controller for controlling operation of the laser drive circuit for signal reproduction and signal recording based on the output of the error correcting circuit. The system controller successively sets the laser powers to at least three different values, obtains evaluation data for each laser power, approximates the relationships between the laser powers and the evaluation data to a quadratic curve, whereby an optimum laser power is derived corresponding to a vertex of the quadratic curve. Accordingly the optimum reproduction power and recording power are set, to thereby record and reproduce signals with high accuracy.
