Abstract

This invention discloses an optical servo writer. The optical servo writer includes an optical pickup head for rotationally moving over and writing servo data in an optical flat data-storage medium. The optical servo writer further includes a clock head for providing clock signals to the pickup head and to write clock signals in the clock disk. The optical servo writer further includes a control circuit for controlling The optical pickup head for writing the servo data on The optical flat data-storage medium. The optical servo writer further includes a servo pattern layout circuit for controlling The optical pickup head for writing the servo data on The optical flat data-storage medium with predefined servo patterns. The optical servo writer further includes a derived index control circuit for deriving indices from a fixed index provided on The optical flat data-storage medium. The optical servo writer further includes a fixed index and clock track circuit for providing a fix index and a clock signal for controlling The optical pickup head for writing the servo data on The optical flat data-storage medium. The optical servo writer further includes a head move circuit for controlling a movement of The optical pickup head for writing the servo data on The optical flat data-storage medium. The optical servo writer further includes a medium movement circuit for controlling a linear movement of the optical flat data-storage medium for writing the servo data on the optical flat data storage medium.
