Abstract
A digital data recording control system reads music data from a CD and records (i.e., copies) the music data onto an SD card. The CD also stores an ISRC that specifies the content of the CD, that is, the music data present on the CD. The digital data recording control system includes: a recording number information storage unit for associating the ISRC with a number of times the music data has been recorded onto an SD card; a limit information storage unit for storing information showing a limit on a number of times the music data is permitted to be recorded; and a record judging unit for: (1) having a digital data reading unit read the ISRC from the CD and, if a number of times associated with the read ISRC is lower than the limit, read the music data from the CD; and (2) having a recording unit convert the read music data into an MP3 format and record the converted music data onto the SD card.
