摘要： In a navigation-related processing, when it is necessary to access a navigation data area 121 in a hard disk device, an access data amount determining portion 211 determines whether the navigation-related processing includes access by a predetermined amount or more of data. When the determination result is affirmative, an access restriction instructing portion 212 sends a hard disk access restricting instruction to a disk recording processing portion 221. In a state where the access of the disk recording processing portion 221 to an additional-function data area 122 of the hard disk is restricted, a navigation processing section 210 accesses the navigation data area 121. As a result, even when a navigation-related processing and a specific additional function-related process other than a navigation function are concurrently performed, it is possible to provide navigation information well.

摘要： An imaging unit captures an image of an entire recording surface of an optical recording medium. An image storing unit stores the image captured as one image of a recording surface image. A track-information calculating unit calculates a virtual center point and an actual track pitch of the optical recording medium. An image-analysis-path generating unit matches a center of an image analysis path with the virtual center point of the recording surface image stored. An image analyzing unit performs an image analysis of the pits sequentially from an innermost periphery according to the image analysis path, and converts the pit arrangement information of the track into a digital signal, and stores the digital signal converted.
