    摘要： In step S1, the address generator generates address information composed of a sync signal which is recorded on an optical disc, address data and an error correction code for the address data, pre-encodes and supplies it to a modulator. At the same time, a carrier signal generator generates a carrier signal which is to carry the address information, and supplies it to the modulator. In step S2, the modulator makes MSK modulation of the carrier signal supplied from the carrier signal generator on the basis of the pre-encoded address information supplied from the address generator, and supplies a resultant MSK modulation signal to a wobbling unit. In step S3, the wobbling unit forms, on the optical disc, a spiral groove wobbled adaptively to the MSK modulation signal supplied from the modulator. In this optical disc, a given address can be accessed quickly and accurately.

    摘要翻译： 在步骤S1中，地址发生器产生由记录在光盘上的同步信号，地址数据和地址数据的纠错码组成的地址信息，并对其进行编码并将其提供给调制器。 同时，载波信号发生器产生携带地址信息的载波信号，并将其提供给调制器。 在步骤S2中，调制器基于从地址发生器提供的预先编码的地址信息，对从载波信号发生器提供的载波信号进行MSK调制，并将得到的MSK调制信号提供给摆动单元。 在步骤S3中，摆动单元在光盘上形成自适应于从调制器提供的MSK调制信号摆动的螺旋槽。 在该光盘中，可以快速准确地访问给定的地址。

    摘要： Outputs of first and second photodetectors (1,2) are supplied to first and second normalizing circuits (8,9) and are also added by an adding circuit (7). An output of the adding circuit (7) is supplied to the normalizing circuits (8,9). By the output supplied from the adding circuit (7) to the normalizing circuits (8,9), the outputs supplied from the photodetectors (1,2) to the normalizing circuits (8,9) are normalized. A subtraction is performed between the outputs of the normalizing circuits by a subtracting circuit (11).

    摘要： The present invention is directed to a writable optical disk recording apparatus in which an output power of a laser beam is controlled even during a recording period. A reproduced (reflected) signal from a matrix circuit (12) is supplied to level hold circuits (37), (38). The level hold circuits (37), (38) are controlled at predetermined timings relative to recording EFM (eight-to-fourteen modulated) signals of bit lengths and under the control of a microcomputer (CPU)(31). Signals from the level hold circuits (37), (38) are supplied to a calculating circuit (39) which calculates, for example, a difference or ratio between the two signals. A calculated value is stored in a memory (40). The value stored in the memory (40) and a value newly calculated by the calculating circuit (39) are compared with each other by a subtracting circuit (41). A compared output is selected by a switch (34) and then supplied through a subtracting circuit (35) to a laser driver (3).

    摘要： An optical disc recording apparatus for recording information signals on an optical disc having an optical recording medium with a larger thermal time constant, such as an organic dyestuff base material, by irradiating the disc with a recording light modulated by signals produced by eight fourteen modulation of information signals, is disclosed. The apparatus includes a recording pulse forming unit for forming recording pulses from the eight fourteen modulated signals, which recording pulses are of pulse widths shorter than the eight fourteen modulated signals by a pulse width corresponding to the elongation from the regular length of a pit formed on the recording medium on the basis of the eight fourteen modulated signals, and an optical head supplied with the recording pulses formed by the pulse forming unit for producing the light which has been eight pulse width modulated by the recording pulses.
