摘要： A burst error-correcting capability is largely improved. At least the even-number row and at least the odd-number row of the data block which is a set of data sectors are separated. An outer parity is created for each column and an inner parity is created for each row. Then, the outer parity is scattered with respect to each of the sectors of the data block to be interleaved.

摘要： A basic data structure in a lead-in area is made coincident with each other in all of a read only type, write once type, and a rewritable type. The lead-in area is divided into a system lead-in area and a data lead-in area. A track pit and a pit pitch of pits in the system lead-in area are made longer than those in the data lead-in area. In the system lead-in area, a reproduction signal from a bit is detected in accordance with a Level Slice technique, and, in the data lead-in area and data area, a signal is detected in accordance with a PRML technique. In this manner, in any of the read only type, write once type, and rewritable type, there can be provided an information recording medium and an information reproducing apparatus or information recording and reproducing apparatus therefor, capable of a stable reproduction signal from a lead-in area of the write once type recording medium while maintaining format compatibility.

摘要： Content data is moved from a first recording medium to a second recording medium, the first recording medium recording an encrypted content (key is first key), a first encrypted key (key is a fourth key which is generated from a second key and a third key), and a second encrypted key (key is the third key). The method comprises decrypting the encrypted content and the second encrypted key which are read from the first recording medium to obtain the plain content and the second key, transmitting the plain content and the second key to the second recording medium, and deleting the second encrypted key from the first recording medium.

摘要： An information storage medium (1) has tracks in which information is recorded. The tracks are formed as a groove section (2) and a land section (3). The groove section (2) has a synchronous structure in which wobbles (2a) and (2b) formed on both walls of the groove section (2) are not displaced from each other in the circumferential direction of the medium, and the land section (3) has an asynchronous structure in which wobbles formed on both sides of the land section (3) are displaced from each other. A good signal is reproduced from each of the groove and land sections.

摘要： A data transmission system for transmitting information data with a parity of an error correcting code for correcting an error in the information data. A read-out controller controls a transmitter to transmit information data and a parity so that each data component of the information data obtained by dividing the information data of one data block area into a plurality of data components and each parity component of the parity obtained by dividing the parity of one block area into a plurality of parity components are transmitted at intervals of each sector having a sector address. The sector is defined as an data area obtained by dividing one data block area of a predetermined data amount into a plurality of sectors each having an identical data amount.

摘要： A digital modulation apparatus applies a method for converting data words to runlength-limited code words using plural conversion tables. The data words are converted to code words that significantly suppress the low frequency component of the final nonreturn-to-zero inverted signal.This digital modulation apparatus includes ROM tables for storing plural conversion tables containing the runlength-limited code words corresponding to the data words; end-runlength memories and evaluators for determining whether the runlength-limit constraints are satisfied in the interconnection between two consecutive code words when the data words to be converted are supplied; and a DSV controller for storing each of the code words that can be selected from two conversion tables to buffer memories when the runlength-limit constraints are satisfied, and selecting the code words wit the greatest effect suppressing the low frequency component in the obtained signal when the code words are NRZI converted.

摘要： A control apparatus for a recording medium drive motor in a digital information reproducing apparatus. The apparatus controls a rotation speed of the recording medium at a prescribed constant linear velocity in using a reproduced signal from the medium without employing a detector for detecting the position of a pick-up device used therein and without being affected by an unexpected level change of the reproduced signal. The apparatus includes a motor for driving the recording medium having a digital information recorded thereon in the form of a run length limited pulse code modulation, a pick-up for reproducing a digital signal from the recording medium driven by the motor, a detector for detecting a predetermined limited cycle length of the digital signal from the reproduced signal by the pick-up, and a controller for controlling the rotation speed of the motor so that the limited run length of the reproduced digital signal is kept at a predetermined value.
