  • CD-ROM Drive and a control method for optimally controlling the spindle motor
    Patent number: 5621710
    Abstract: CD-ROM drive, including a pick-up for detecting recorded data from a CD-ROM, a control signal generation part for generating a acceleration/deceleration control signal, a driving extent control signal, and a guaranteed frame synchronizing signal by processing a high frequency signal received from the pick-up, an acceleration/deceleration control part for receiving the acceleration/deceleration control signal, the driving extent control signal, and the guaranteed frame synchronization signal from the control signal generation part, outputting the acceleration/deceleration control signal and the driving extent control signal as a driving signal and a driving extent signal respectively in case mode is not a searching mode but a normal linear velocity mode, and generating a driving signal and a driving extent signal based on a result obtained by subjecting the acceleration/deceleration control signal, the driving extent control signal, and the guaranteed frame synchronization signal to an operation so that the gu
