Abstract

When an audio signal and music piece name information are recorded onto a CD-R, timing for inputting the music piece name information is not restricted to timing just before “finalize”. An ID is allocated to the CD-R inserted into a recorder and written into a PMA and a memory. The audio signal is recorded into a PGA on the CD-R. The music piece name information and the like are inputted by text data and stored into the memory in correspondence to the ID. Upon “finalize”, the text data is read out from the memory and written as TOC information into a lead-in on the CD-R. In case of ejecting the CD-R without finalizing, a track number, start time, and end time are recorded into the PMA. The ID and the text data are held in the memory. When this CD-R is subsequently inserted, they can be read out from the memory on the basis of the ID. Before “finalize”, the text data which is recorded as TOC information can be inputted anytime.

Claims3

Dependent claims

A recording and reproducing apparatus for recording and reproducing data onto/from a recording medium having a recording area where a program can be recorded and a management area where management information for managing the program recorded in the recording area is recorded, comprising:

recording means for recording an identifier that is peculiar to the recording medium into said management area and the program into said recording area upon recording;
memory means for holding the identifier peculiar to said recording medium and information regarding the program which is recorded into said recording area in correspondence to each other;
reproducing means for reproducing an identifier of said management area on the recording medium inserted after said recording medium was once ejected before the management information in said management area is updated;
comparing means for comparing the identifier reproduced by said reproducing means with the identifier held in said memory means;
and
control means for controlling said recording means so that the information regarding the program which is recorded into said memory means in correspondence to the identifier peculiar to said recording medium is recorded as said management information when it is decided by said comparing means that the identifier reproduced by said reproducing means and the identifier held in said memory means coincide.
