Abstract:
A disc recording apparatus, comprising:a disc shaped recording medium having tracks that are divided into a plurality of sections;means for recording data to said disc;discriminating means for discriminating whether the section of the disc under recordation is defective, the discriminating means utilizes turbulence of an error signal for said discrimination of the section for a defect, wherein said turbulence of said error signal is detected by an optical block for recording data on the disc, said discriminating means sensing defective sections by sensing a turbulence of said error signal exceeding a predetermined amount; andcontrolling means for controlling said recording means wherein if said discriminating means discriminates that the section under recording is a defective one, then the recording is stopped and a section offset is calculated from said defective section to identify a calculated section that follows said defective section, and said recording means is moved to said calculated section where recordation begins again;wherein said calculated section immediately follows said defective section on said disc.
