Title:
OPTICAL DISC RECORDING AND REPRODUCING DEVICE
Document Type and Number:
Japanese Patent JP3405358
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To continue recording or reproducing data while securing continuity in the data even when abnormalities happen in recording or reproducing operations such as track jumps.
SOLUTION: If an abnormality detector 30 detects a track jump when recording data on an optical disc 2, data read to the memory 14 is stopped until the operation returns normal based on the detected track jump. When the read is resumed to memory 14, data are recorded on an optical disc 2 seamlessly over the stop time caused by the track jump based on the recording position control of the optical disc 2 by a system controller 7. When reproducing, the data are reproduced from the optical disc 2 continuously regardless of the points of record stop and start.
