摘要： Disclosed is a digital adaptive filter and a method of cancelling an echo component generated by a partial return of a transmission signal to a receiving side. The digital adaptive filter comprises: a main memory unit for storing a first echo replica which can be stored or read by using the parallel signal from a main tap unit as an address signal, at least one submemory unit for storing a second echo replica which can be stored or read by using the parallel signal from said subtap unit as an address signal, and an adding circuit for adding the first echo replica and the second echo replica. The second echo replica stored in the at least one submemory unit has a greater precision than the precision of the first echo replica stored in the main memory unit, and thus the accumulated error due to memory division can be reduced. Instead of or accompanied by the greater precision, the contents of the main memory are updated directly based on the error between the pseudo signal and an input signal or based on a step size corresponding to the error, depending on whether the error is relatively large or relatively small, respectively.

摘要： An optical disk apparatus which has first and second light-emitting elements for emitting laser beams, and records data on a recording medium with laser beams from the first and second light-emitting elements includes first and second recording abnormality detectors, first and second protective circuits, and abnormality signal synchronization circuits. The first and second recording abnormality detectors detect abnormalities of recording by the first and second light-emitting elements from beams reflected by the recording medium during execution of recording. The first and second protective circuits immediately stop recording being executed by the first and second light-emitting elements, and protect data on the recording medium when the first and second recording abnormality detectors detect abnormalities. The abnormality signal synchronization circuits inform the second and first protective circuits of abnormalities in synchronism with completion of recording being executed by the second and first light-emitting elements when the first and second recording abnormality detectors detect the abnormalities.

摘要： An optical disk apparatus for performing recording and reproduction of information on an optical disk is disclosed. The optical disk has a sector format which consists of a sector mark area in which a sector mark is recorded and an address area in which a plurality of VFO segments and ID segments are alternately provided. The apparatus comprises a sector mark detector, a read gate controller, a PLL controller and an address information detector. The sector mark detector detects the sector mark. The read gate controller controls a read gate to be opened and closed. The read gate enables readout of information from the VFO segment when it is opened. The PLL controller initiates synchronization of a signal read from the VFO segment with a PLL in response to the opening of the read gate. The address information detector detects an address identifier recorded in the ID segment. If the address information detector cannot detect the address identifier, the read gate controller closes the read gate and opens the read gate at a timing corresponding to the VFO segment located immediately after the ID segment in which the address identifier cannot be detected.

摘要： An optical disk apparatus having an optical head for reading and writing signals on an optical disk and a signal processing unit for performing predetermined signal processing on the signals is disclosed. The apparatus includes a first controller, a second controller, a detector, and an adjuster. The first controller controls the optical head to write a predetermined signal on a predetermined area of the optical disk with various levels of recording power of the optical head. The second controller reproduces the predetermined signal written on the predetermined area of the optical disk. The detector attempts to detect a predetermined signal pattern having a predetermined period from the reproduced signal with different slice levels. The adjuster determines a resolution of the reproduced signal in accordance with a slice level with which the signal pattern can be detected and automatically adjusts the recording power of the optical head based on the determined resolution.
