Abstract: An apparatus for reproducing an optical recording medium includes a system controller. If a digital audio signal is present in a shockproof memory, the system controller sets a first search target address so as to be connected to an absolute time address of a digital audio signal which is last accumulated in the shockproof memory. If there is no digital audio signal in the shockproof memory, the system controller calculates a second search target address based on the absolute time address of the digital audio signal which is last accumulated in the shockproof memory and an elapsed time since no digital audio signal remains in the shockproof memory, and moves the optical pickup to a position on the disk indicated by the second search target address calculated.

Abstract: A computing unit (130) controls a servo controller (114) to move an optical pickup (111) to the innermost circumference of a mounted recording disk and acquires a recording information from a lead-in area of a first session by a recording-information acquiring unit (132). When the computing unit (130) determines that the recording disk (1) is a multi-session type according to the recording information, the computing unit (130) acquires a recording information of a second session and compares the recording information by an information determining unit (133). As a result of the comparison, if the recording information is determined as abnormal on account of copy protection, the computing unit (130) does not store the recording information of the second session, but acquires a program information based on the recording information of the first session and reproduces the program information.

Abstract: Disclosed is a disk drive apparatus which has a manual search function with improved operability. Upon manual search for information TNO(n+1) recorded on the outer periphery of a information write/read medium to information TNO(n) recorded on the inner periphery, there may be an gap (no sound) portion in the information between the outer and inner peripheries. In this case, the information is searched by the front-end position Pb on the outer periphery. Thereafter, no search is performed on the gap (no sound) portion through skipping from the front-end position Pb to the terminal end position Pc of the information TNO(n). Thus, only necessary information is continuously searched upon the manual search without searching the gap (no sound) portion which is not necessary for the user. Thus, the user is provided with improved operability.
