PROBLEM TO BE SOLVED: To perform read-out of data from an optical disk with appropriate speed in accordance with required data transfer speed. SOLUTION: This is an optical disk reproducing method in an optical disk apparatus performing reproduction of data from the optical disk according to a received command, the method is provided with an optical disk discriminating process in which a kind of an optical disk is discriminated, an operation speed setting process in which operation speed of the optical disk apparatus is set to operation speed in accordance with a kind of the discriminated optical disk, a command receiving interval measuring process in which command receiving interval of the received command is obtained, a comparing process in which relation between operation speed decided by the operation speed setting process and a value in accordance with the command receiving interval is obtained, a speed switching process in which the operation speed is switched to speed in accordance with a result obtained in the comparing process, and a read-out process in which data from the optical disk is read out.
