  • Publication number: 20060187774
    Abstract: A recording apparatus includes: recording means having a drive part including rotational drive means for rotating an optical recording medium in order to record data onto the optical recording medium; data coding means for coding data; and recording control means for storing the coded data into storage means and controlling the recording means to record the data stored in the storage means onto the optical recording medium. The recording control means includes overall control means for controlling the recording control means overall and servo control means for servo-controlling the drive part of the recording means. In the recording-standby state standing by to store the coded data, the overall control means stops operation of the servo control means, and at the same time, servo-controls the rotational drive means.
