    摘要： In order to provide an audio device capable of making more effective use of non-compressed audio data and compressed audio data, according to the present invention, compressed audio data as computer data is stored in a data track in a Mixed-mode CD. By allowing a playback apparatus to recognize the presence of the compressed audio data, both the compressed audio data and non-compressed audio data stored in a CD-DA track are played back.

    摘要： In a multi-session disc including both audio session and data session, the data session is correctly recognized and accessed. The reproducing apparatus is a reproducing apparatus of a multi-session disc mixing a session of first type recording first data and a session of second type recording second data different from the first data, comprising an optical pickup for accessing the session of first type and the session of second type, a judging unit for judging a type of the session accessed by the optical pickup, and a limiting unit for limiting the session of first type to a reproducible session when the session of second type judged by the judging unit is present at an access position after the session of first type.

    摘要： A computer system is disclosed comprising a host connected to a disk drive, the disk drive comprising a disk having a disk surface. The disk drive further includes a controller and a channel integrated circuit chip. The controller includes a controller port. The channel integrated circuit chip includes an input for receiving a time-multiplexed analog read signal. The time-multiplexed analog read signal is processed to generate data symbols representing recovered servo data and recovered user data. The channel integrated circuit chip includes a channel port for transferring both the recovered servo data and the recovered user data. The disk drive further includes a communication bus connected between the channel port and the controller port. The channel port transfers both the recovered servo data and the recovered user data to the communication bus. The communication bus transfers both the recovered servo data and the recovered user data to the controller port.
