Abstract:
1. A labeling method for a blu-ray disc comprising: selecting an initial radius on a blank area of the blu-ray disc, and determining a pattern; calculating an initial physical sector number using the initial radius, and transforming the pattern into a description data, wherein the initial physical sector number is determined by a computer using a formula: wherein the PSN start represents the initial physical sector number, the PSN ref represents a reference physical sector number, the r dividing a sequential recorded region of the blu-ray disc into at least two sequential recorded regions according to the initial physical sector number and a size of the description data, and updating information of the at least two sequential recorded regions in a table of content, wherein an initial position of one of the sequential recorded regions is the initial physical sector number, and a length of the one of the sequential recorded regions is the size of the description data; and writing the description data from the initial physical sector number.
