Patent ID: 7916583

Claim:
A method of reproducing data recorded on an optical disk loaded in an optical disk device, the method comprising: inputting a start instruction at a first time point during reproducing the data recorded on the optical disk; starting an intermittent reproduction in which data reproduction for a first fixed time period and data skipping for a second fixed time period are alternately performed and repeated, from a first data position on the optical disk corresponding to the first time point; storing information concerning the first time point; inputting a restart instruction during performing the intermittent reproduction; determining a second time point which is different from the first time point with reference to the information when the restart instruction is input; and starting the intermittent reproduction again from a second data position on the optical disk corresponding to the second time point, wherein: the second time point is located within the second fixed time period; and the second time point is shifted from the first time point by the first fixed time period.
