Abstract
A method of recording data on an optical storage medium writes different types of data to the same area on the optical storage medium. The data to be written are successively stored in a data buffer in accordance with the sequence of the identification data of a data sector. The same area can be a lead-in area, a data area or a lead-out area. Therefore, a recording circuit can read out the data from the data buffer in accordance with the sequence of corresponding identification data and write them to corresponding tracks on the optical storage medium.
Claims18
A method of recording data on an optical storage medium, comprising the steps of:
- storing different types of data successively temporarily in a data buffer according to the sequence of identification data before the data are written to an optical storage medium;
- and
- writing the data stored in the data buffer to corresponding tracks on the optical storage medium after the data are encoded.
An apparatus for recording data on an optical storage medium, comprising:
- a data pre-processing unit restructuring different types of data to be written to identical data sectors on an optical storage medium according to the sequence of identification data (ID) for each data sector;
- a data buffer controller storing the restructured data into a data buffer;
- a encoder controller reading the restructured data from the data buffer through the data buffer controller and encoding the restructured data;
- and
- a recording circuit successively reading the restructured data from the data buffer through the data buffer controller and writing the restructured data to corresponding tracks of the optical storage medium.
