ABSTRACT:
A method of recording digital signals on a disk which has at least a first recording surface and a second recording surface both being readable from a same side of the disk. The digital signals are in the form of a data frame which includes at least n data blocks (n is a natural number). The method includes the steps of assigning block addresses to a series of the data blocks included in the data frame in order, respectively; recording, at the head of the data frame, a lead-in block including information indicating a number of recording surfaces, an end data block address of the first recording surface, and an end data block address of the data frame; recording first to m-th data blocks (m is a natural number, 0<m<n) including the respective block addresses of the data frame on the first recording surface of the disk in a first radial direction of the disk; and recording (m+1)th to n-th data blocks including the respective block addresses of the data frame on the second recording surface of the disk in a second radial direction of the disk opposite to the first radial direction of the disk.
