ABSTRACT:
A method of recording digital signals on a disk having at least a first recording surface and a second recording surface. The digital signals are in the form of a data frame including a lead-in block and n data blocks. The lead-in block has a same format as the n data blocks. The method includes the steps of assigning n block addresses to respective ones of the n data blocks, assigning, to each of the n data blocks, information identifying an area on the disk in which a respective one of the n data blocks is to be recorded, recording m data block (0<m<n) of the n data blocks on the first recording surface of the disk, recording remaining (n-m) data blocks of the n data blocks on the second recording surface of the disk, and recording the lead-in block at the head of the data frame. The lead-in block includes information identifying an area on the disk in which the lead-in block is to be recorded, a number of recording surfaces, the block address of one of the m data blocks recorded last on the first recording surface, and the block address of a last one of the n data blocks in the data frame.
