Method and apparatus for recording data on writable compact disc

摘要

A method of recording data on a compact disc is provided. Data of 1 byte is modulated to p-channel bits. Data is recorded when a minimum mark length is greater than 0.5 µm and smaller than 1.0 µm, p/q is greater than 4.5 and smaller than 8 when the minimum mark length corresponds to q-channel bits, and format efficiency is greater than 0.6 and smaller than 1.0. Thus, data can be recorded on an existing compact disc at a higher density.
