Title: Optical disk apparatus
Inventor: FURUKAWA FUMINOBU
IPC: G11B19/04
Filed: 2002-06-18
Abstract: PURPOSE: An optical disk device is provided to increase probability of correcting a reading error resulted from the deviation of a recording-resuming position. CONSTITUTION: When the amount of data in a buffer becomes below the predetermined amount of data, a buffer-underrun-detecting circuit(111) regards this state as a buffer-underrun condition. According to the result, a recording interrupting and resuming circuit(108) detects an end position of the last pit for recording and stores the position in a time information memory(109), and an optical disk device becomes in a pause condition of recording. When the buffer-underrun condition is released, an optical disk device releases the pause condition of recording, reads the position of interruption of recording from the time information memory, synchronizes information recorded on an optical disk(101) and the new information to be recorded, and resumes recording by setting a predetermined interval between the recorded information and the information to be recorded.
