Apparatus for and method of controlling writing of data when error occurs in an optical drive

An apparatus for controlling a write mode in an optical drive when an error occurs, the apparatus comprising:

• means for monitoring for an error during a write mode operation;
• means for controlling the storing of predetermined data required for restarting the write mode if it is determined by a signal generated by the monitoring means that the write mode is stopped;
• and
• means for controlling the write mode so that the write mode is restarted based on the predetermined data.

An apparatus for controlling a writing of data in an optical drive, the apparatus comprising:

• a buffer;
• a memory;
• an encoder which stores data to be written to an optical disc in the optical drive in the buffer;
• a microcomputer;
• which:
• controls the writing of the data from the buffer to the optical drive,
• determines whether a subcode of the encoder corresponds with an absolute time in pregroove (ATIP);
• and
• stops the writing of the data if the subcode of the encoder does not correspond with the ATIP.

An apparatus for controlling a writing of data in an optical drive, the apparatus comprising:

• a buffer;
• a memory;
• an encoder which stores data to be written to an optical disc in the optical drive in the buffer;
• a microcomputer;
• which:
• controls the writing of the data from the buffer to the optical drive,
• stops the writing of the data on occurrence of one of a predetermined number of errors;
• stores predetermined data in the memory for use in restarting the writing of the data if the writing of the data is stopped;
• determines whether the occurrence of the one of the predetermined number of errors is due to jumping of a track or a subcode in the encoder;
• and
• restarts the writing of the data based on the stored predetermined data if the writing of the data is stopped due to the jumping of the track or a subcode in the encoder.

A method of controlling a writing of data in an optical drive having a buffer which temporarily stores data transmitted by a host computer and an encoder which stores the data from the host computer in the buffer, the method comprising;

• transmitting the data from the host computer to the buffer;
• writing the data from the buffer to a disc installed in the disc drive;
• stopping the writing of the data on occurrence of one of a predetermined number of errors;
• storing predetermined data for use in restarting the writing of the data if the writing of the data is stopped;
• determining whether the occurrence of the one of the predetermined number of errors is due to jumping of a track or a subcode in the encoder;
• and
• restarting the writing of the data based on the stored predetermined data if the writing of the data is stopped due to the jumping of the track or the subcode in the encoder.
