摘要： A groove track and a land track are alternately and spirally formed on an information recording medium. On the land track neighboring the groove track, pre-information indicating position information of a track on a disc is formed as a prepit. On the information recording medium, an embossed area is formed so that information about a copyright and for preventing an illegal copy cannot be rewritten. In the embossed area, an embossed configuration including a pit and a space of predetermined depths is formed. The prepit in the embossed area is formed so that the prepit has an optimized configuration according to a pit length and a space length in the embossed area which the prepit neighbors. Consequently, interference between the embossed configuration and the prepit can be prevented even in a case that the prepit is formed in addition to the embossed configuration in the embossed area.

摘要： An information recording device and method capable of forming a recording mark by suppressing thermal interference. The device applies a laser beam to a recording medium and forms a recording mark in accordance with a recording signal. The device includes a light source for emitting the laser beam, signal generation elements for generating a recording pulse signal according to the recording signal, and drive elements for driving the light source according to the recording pulse signal. The recording pulse signal has a mark period for forming the recording mark and a space period. The recording pulse signal makes the level in the entire space period equal to or shorter than a predetermined length and a part of the space period longer than the predetermined length to be off level. While the recording pulse signal is off level, the recording medium is cooled down, thereby suppressing the affect of thermal interference.

摘要： Based on a recording signal, a recording pulse signal, which includes a top pulse located at a front end portion and having a first magnitude, a last pulse located at a back end portion and having the first magnitude, and an intermediate bias portion located between the top pulse and the last pulse and having a second magnitude, is generated. Based on the recording pulse signal, a light source is controlled, and a laser pulse is irradiated on a recording medium. Recording marks corresponding to the recording signal are formed on the recording medium. In generating the recording pulse signal, when the recording medium is rotationally driven, a position of the top pulse is shifted ahead of a position of the top pulse when the recording medium is rotationally driven at the first rotation speed, when the recording medium is rotationally driven at the second control speed.

摘要： An error detector at a receiver comprises a feedback shift register. A shift direction in the feedback shift register is opposite to a shift direction at a transmitter in generating a transmission bit string by using a specified generator polynomial. A reception bit string is inputted to the feedback shift register in reverse order to the transmission bit string was generated at the transmitter so that errors in the reception bit string is detected by obtaining the remainder. Another error detector at a receiver comprises first and second feedback shift registers. Respective shift directions in the first and second feedback shift registers are the same as and opposite to a shift direction at a transmitter in generating a transmission bit string. The reception bit string is inputted to the first feedback shift register in the same order in which the transmission bit string was generated, while the reception bit string is inputted to the second feedback shift register in reverse order to one which the transmission bit string was generated. Errors in the reception bit string are detected by comparing respective remainders obtained by the first and second feedback shift registers. This reduces the processing time required for the error detection and increases efficiency in detecting errors in transmitted data.

摘要： An information recording medium is provided with a wobbled track, wherein at least a part of the track is subjected to wobbling based on a wobble signal in which at least a part of recording information is randomized. Each track is wobbled at a randomized frequency, so that a frequency of a wobbling signal obtained from the wobbled track is randomized. As a result, the influence of crosstalk between adjacent track is reduced.
