Method for recording digital signals on multiple-layered disks

A method of recording digital signals on a disk,

• the disk having at least a first recording surface and a second recording surface,
• the digital signals being in the form of a data frame,
• the data frame including at least a lead-in block and n data blocks (n is a natural number),
• the lead-in block having a same format as the n data blocks,
• the method comprising 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 blocks (m is a natural number, 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 including
• information identifying an area on the disk in which the lead-in block is to be recorded,
• information identifying a number of recording surfaces,
• information identifying the block address of one of the m data blocks recorded last on the first recording surface, and
• information identifying the block address of a last one of the n data blocks in the data frame.
