摘要： A method for controlling the recording speed of a multi-layered optical disc divides a multi-layered optical disc into a plurality of zones with each zone having a corresponding recording speed. It is then determined which zones need the recording speed to be reduced according to the quality of the optical disc. When the optical drive records data onto an inferior quality zone, it reduces the recording speed to guarantee the reliability of recorded data and enhance recording quality. When the optical drive records data on the next recording layer and has passed the zone that corresponds to the inferior quality zone of the previous recording layer, it increases the recording speed. Thereby the method ensures both quality and efficiency. Furthermore, the recording speed of each subsequent zone of the next recording layer corresponds to the recording speed of each previous zone of the recording layer.

摘要： The specification discloses a braking method for a single-phase motor, which is applied to a single-phase DC brushless motor driven by a three-phase motor driving IC. The invention uses a control unit to compute the rotational speed of the single-phase motor according to a rotation number signal generated by the motor rotational axis. When the rotational speed is below a threshold, the motor driving IC is controlled to stop rotating the single-phase motor. Through the single-phase motor braking method disclosed herein, the problem of unable to determine the rotational direction of a single-phase motor within a three-phase motor driving IC existing in the prior art can be solved by merely modifying the program in the control unit without adding system elements. Since currently the single-phase DC brushless motor and the three-phase motor driving IC have competitive superiority in prices, if the three-phase motor driving IC can directly drive the single-phase DC brushless motor without requiring additional system elements the whole system cost can be lower. On the other hand, this method can avoid the delay problem due to fewer single-phase motor driving IC manufacturers on the market.

摘要： The present invention discloses read and write power control methods and system for an optical recording device that records information on an optical disk having read-only areas. The read and write power control methods respectively introduce the steps of determining a specific level of a former power control signal output based on a former power control, and then according to the specific level, setting a predetermined level of a power control signal to induce a present power control for rapidly outputting a proper power of the pick-up head. Accordingly, the level transition of the read/write power control signal can be shortened and even eliminated. An unstable read/write power output for the pick-up head can be avoided.
