专利汇可以提供Searching system of digital audio disk专利检索,专利查询,专利分析的服务。并且PURPOSE: To decrease the number of times of overruns and returns of a reproducing head, by substituting the block synchronizing signal for detection of the music number information in case said detection is impossible with the reproducing head and detecting that the reproducing head reaches the position of a desired music number.
CONSTITUTION: A digital audio disk (DAD)1 records the signals in the form of a light reflective bit train, and an optical reproducing head 4 which reads the signals with a laser beam is set movably in the radius direction of the DAD1 by means of a head shifting mechanism 5 and opposite to the recording surface. The signal 9 reproduced by the head 4 is fed to a signal processing circuit 10. The block synchronizing signal 21, the control/address signal 22 and the music signal 23 are separated and extracted through the circuit 10. At the same time, the clock signal 11, etc. necessary for processing of signals are supplied to the circuit 10.
