摘要

PROBLEM TO BE SOLVED: To solve the problem that in a conventional method of writing information to an optical disk 2 having a user storage space USS. SOLUTION: The method includes a step of dividing the storage space of the optical disk 2 into one or more sections 80; 181, 182, 183, 184 where write of a certain application is allowed and one or more sections where write is not allowed. The location and extent of the allowed section is either fixed in a format or determined by one or more parameters BA, L, VAPT stored on a disk. A signal processing system 120 of a video recorder apparatus 100 determines an allowed storage area VASS for the present disk before trying write operation to the disk 2, and selects a free area 72 for writing only within the allowed storage area.
