  • Optical recording and reproducing apparatus for synchronizing recording on subsequent unrecorded sectors
    Patent number: 5276667
    Abstract: Disclosed is an optical recording and reproducing apparatus capable of recording in a position which is properly synchronous with the position of the last pit in a sector on which a recording was made, the first pit in a sector on which a recording is to be subsequently made. This apparatus is characterized by a recording circuit having a data demodulating circuit which includes a synchronizing signal separating circuit. The synchronizing signal separating circuit outputs a synchronizing signal on the basis of a pit detection signal generated in response to the detection of pits formed on a track of a recording medium and representing data to be recorded.
