摘要： A data extracting circuit for converting an analog signal derived from a D.C. component-free modulated digital signal stored on a recording medium, into a D.C. component-free digital signal with a comparator for comparing the analog signal with a reference signal to provide a compared signal. A phase inverter receives the compared signal and provides a first signal component which is in-phase with the compared signal, and a second signal component which is phase-inverted with respect to the compared signal. A clipping circuit limits the amplitude level of the first and second signal components to a predetermined level and provides first and second limited signal components. An integrating circuit separately integrates the first and second limited signal components and provides first and second integrated signals. An error amplifying circuit determines the difference between the first and second integrated signals and provides a signal corresponding to this difference to the comparator as the reference signal. The D.C. component-free digital output signal is derived from the first signal component.

摘要： Reinforcement of a system renewability is realized skillfully utilizing properties peculiar to a system. As a result, there is produced such a new effect as to similarly reinforce required specification with respect to copyright protection of a content recorded in a medium for exclusive use in reproduction and a recordable medium. In a system which encrypts information such as a content to record/reproduce the information, design is made so that encryption/decryption processing information differs for a device (software (S/W) main body device) whose main body is software constituted of a recording/reproducing drive of a recording medium and a personal computer (PC), a device (hardware (H/W) main body device) whose main body is hardware integrally containing a drive and data coding/demodulation processing, and the medium for exclusive use in reproduction and the recording medium.

摘要： When detecting a rotational position of a seconds hand, it is determined whether data stored in a register in correspondence with a supply state of a drive current previously supplied to a coil of a stepping motor is “0”. When the data is “0”, the rotational position of the seconds hand is optically detected. When the data is “1”, the seconds hand is rotated one step, and then, the rotational position of the seconds hand is optically detected. Even though the seconds hand is shifted one second, the position detection is executed every two steps.

摘要： A row of the data block which is a set of the data sector is distributed to constitute two blocks. In this case, as a distribution condition, an even-number row block of the even-number sector and the odd-number row block of the even-number sector, the odd-number row block of the even-number sector and an even-number row block of the even-number sector are obtained. Then, the block is aggregated in the transmission order, and an outer parity is scattered to each sector to form an interleaved form.

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.
