ABSTRACT:
A control system for dynamically regulating an operating condition of a device used with and controlled by a host computer system. The inventive system includes a sensor arrangement for detecting the desired operating condition of the device and providing a signal in response thereto. A control system dynamically regulates the operation of the device in response to commands generated by the host system and the sensor output signal to maintain the operating condition of the device within predetermined parameters. In a particular implementation, the advantageous teachings of the present invention are incorporated in an optical drive system. One or more sensors are used to detect the operating temperature of the drive and provide an analog output signal in response thereto. The signal is digitized and input to a microprocessor based control circuit. When the temperature of the drive exceeds a first threshold, the control circuit dynamically adjusts the duty cycle of the drive by inhibiting high temperature write and erase operations. When the temperature of the drive exceeds a second threshold, the control circuit inhibits the lower temperature read and verify operations as well. As a result, the controller maintains the operating temperature of the drive within predetermined parameters which may be controlled by the user through the host computer.
