ABSTRACT:
On loading a CD-ROM, which is a data recording medium, onto a reproducing device, a time information of a sub-code is read out, and then, a time information of a header is read out. In accordance with a difference between the time information of the sub-code and the time information of the header, an offset value is calculated and memorized. When a time information of a target header is given, by adding the offset value to the given time information of the header, a target time information is calculated, and a sub-code, which indicates a time information equal to the target time information, is searched as a target sub-code. On searching the target sub-code, a time information of the header is read out. By these operations, time for accessing is shorten, on being given the time information of the target header and searching the header.
