Title:
METHOD FOR WRITING DATA TO OPTICAL DISK AND OPTICAL DISK DRIVE
Document Type and Number:
Japanese Patent JP3670259
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent a write error by detecting acceleration that occurs an optical disk during writing data in real time and controlling a writing speed on the basis of the detected state.
SOLUTION: When data is written to an optical disk 10, acceleration applied to tracking servo means 40 and 26 and/or focus servo means 42 and 28 is detected. When the detected acceleration exceeds preset reference acceleration, data writing is once stopped, and a writing speed is made slow from the stopped address to resume data writing.
