摘要： On an optical disk medium according to the present invention, address information is recorded along a wobbling track groove 2. The track groove 2 is made up of a plurality of unit sections 22, 23. Each of these unit sections 22, 23 has side faces that are displaced periodically in a disk radial direction. This displacement oscillates at a single period in a tracking direction. However, the displacement pattern differs depending on “each bit of address information (subdivided information)” allocated to each of the unit sections 22, 23.

摘要： In an optical disc drive, a laser light source emits a laser beam having an intensity changeable with the amount of drive current supplied. A first photodetector receives the laser beam reflected from an optical disc, thereby generating a readout signal. A second photodetector receives the laser beam, generates an electric signal representing the power of the laser beam received, and outputs the electric signal as a light quantity detection signal. A feedback control loop compares the level of the light quantity detection signal with a predetermined target value and regulates the drive current such that the level of the light quantity detection signal approaches the target value. In reading data from the optical disc, the target value is changed so as to compensate for a variation of the sensitivity of the second photodetector, thereby controlling the power of the laser beam emitted from the laser light source.

摘要： An apparatus for reproducing information that has been digitally recorded on a storage medium includes first and second waveform equalizers. The first waveform equalizer equalizes a read signal, corresponding to the information read out from the storage medium, thereby outputting a first equalized signal. The second waveform equalizer has an equalization characteristic different from that of the first waveform equalizer, outputs a second equalized signal and is selectively used to extract a read clock signal.

摘要： A data transfer system transfers original data from a first data storage device to a second data storage device. The transfer system includes a compressor, an encryptor, and a controller. The compressor receives the original data from the first data storage device, generates compressed data of a smaller size, and passes the compressed data to the second data storage device. The encryptor makes a predetermined cryptographic key and passes the key to the second data storage device. The encryptor also receives the original data from the first data storage device, encrypts the original data with the cryptographic key and then sends the encrypted data back to the first data storage device. The controller controls the compressor and the encryptor and gives the first data storage device a first erase instruction, telling the first data storage device to erase the original data, in accordance with a first transfer command.
