Abstract

A control method of an optical disc drive system is provided. Firstly, a first write command is issued to burn a first write data including plural data files to an optical disc in an optical disc drive. If a write fail message from the optical disc drive is received after a specified data block of a specified data file is transmitted to the optical disc drive, the transmission of the first write data is stopped. Then, a data amount of the specified data file that has not been transmitted to the optical disc drive is calculated, and a dummy data with the data amount is generated. Then, the dummy data and the other data files that have not been transmitted are burnt to the optical disc.

First claim

What is claimed is:

1. A control method of an optical disc drive system when an optical disc write failure occurs, the control method comprising steps of:
issuing a first write command to burn a first write data to an optical disc in an optical disc drive, wherein the first write data contains plural data files;
if a write fail message from the optical disc drive is received after a specified data block of a specified data file of the plural data files is transmitted to the optical disc drive, stopping transmitting the first write data;
calculating a data amount of the specified data file that has not been transmitted to the optical disc drive, and generating a dummy data with the data amount; and
issuing a second write command to burn a second write data to the optical disc in the optical disc drive, wherein the dummy data and the other data files that have not been transmitted are served as the second write data,
wherein if the optical disc write failure occurs after the optical disc drive receives the specified data block, the optical disc drive stops a writing operation, sets an updated next write address according to a burning end address of the specified data block, records the updated next write address into the optical disc, and generates the write fail message to a host.

2. The control method as claimed in claim 1 , wherein the updated next write address is recorded in a lead-in area of the optical disc.

3. The control method as claimed in claim 1 , further comprising steps of:
the optical disc drive receiving the first write command and the first write data from the host;
controlling an optical pickup head to burn the first write data to a track of the optical disc from a next write address of the optical disc when the optical disc drive performs a writing operation;
the optical disc drive receiving the second write command and the second write data from the host; and
controlling the optical pickup head to burn the second write data to the track of the optical disc from the updated next write address of the optical disc when the optical disc drive performs the writing operation according to the second write command.

4. The control method as claimed in claim 3 , wherein after the second write data is successfully burnt to the track of the optical disc, an address next to a final burning address of the track of the optical disc is set as another updated next write address by the optical disc drive.
