OPTICAL DISC EXCLUSIVE FOR REPRODUCTION

摘要

PURPOSE:To reduce the master disc cutting time and retrieval time at reproduction by recording a track next to the final track of a file management information section recorded from the innermost (outermost) circumference in reverse order as the final track of a data section. CONSTITUTION:The file management information section 4 is recorded from the innermost circumference in a reproducing exclusive optical disc 5 and then the data section 2 comes next. Since no optical head is placed to a non-recording section 6 at reproduction, no guide slot is engraved in the non-recording part 6. In cutting a master disc of the disc 5, the information section 4 is cut from the innermost circumference and then the data section 2 is cut succeedingly without any interval. Then the non-recording part 6 is not cut.
