ABSTRACT:
A signal recording apparatus and a signal recording method for recording moving pictures, such as, a movie, without certifying an optical disc recording medium are provided. A recording section 10 of a signal recording apparatus 1 records moving picture data onto an optical disc. A defective sector detection circuit 31 reads, from the recording medium, a physical block address corresponding to the logical block address of the moving picture data to be recorded and detects an address error. When the address error is detected, an address control circuit 32 stops read counting from an RSPC working memory 14. When the defective sector detection circuit 31 detects a sector of the next good physical block address after detecting the address error, the defective sector detection circuit 31 supplies a restart signal to the address control circuit 32 so that recording starts at this good sector. A random access memory 24 stores physical block addresses of defective sectors, and records a list of the physical block addresses of the defective sectors onto the recording medium after all the moving picture data are recorded.
