Pre-recorded compact disc and copy-limit method thereof

摘要

A copy-limit pre-recorded CD (Compact Disc) and a copy-limit method protect the data recorded on the pre-recorded CD from copied onto a recordable CD. The pre-recorded CD (Compact Disc) includes a data area of the pre-recorded CD and an indivisible file. The storage capacity of a data area of the recordable CD is Z. The indivisible file is stored in the data area of the pre-recorded CD and has a file size Y which approximately ranges between Z+10 MB and Z+100 MB. The copying action is prohibited to proceed when the indivisible file with a size is larger than the storage capacity of the data area of a recordable CD is determined.
