摘要： The present invention offers an optical disk determination circuit that can improve the stability of the operation to detect the peak (pulse signal) of the received light signal, and that can improve the stability of the optical disk determination operation. When determining the type of optical disk corresponding to the depth from the surface of the plane on which a light beam is irradiated to the data recording layer, light is irradiated while varying the focal position of the light beam at a constant velocity in one direction of the depth direction from the surface of the optical disk. The bottom level of the received light signal corresponding to the intensity of this reflected light is clamped at a specified level by the bottom clamp circuit 43. The received light signal with the bottom level clamped is compared with a specified reference voltage Vref by the comparator 45, and the received light signal peak (pulse signal) is detected corresponding to the results of this comparison. The type of optical disk is determined by measuring the difference in this peak (pulse signal) detection time.

摘要： The present invention discloses a fully integrated data synchronization circuit for a disk drive read channel system. The data synchronization system comprises dual data synchronizers to provide read reference clocks. Dual PLL circuits are coupled to the data synchronizers to provide a stable reference frequency to data synchronizers. One of the two data synchronizers is used to obtain leading edge data, while the other is for trailing edge data. Each PLL circuit comprises a phase detector, a charge pump, and a VCO. A loop filter is used in conjunction with a charge pump to control loop characteristics of the PLLs. In an idle mode, one of the PLLs is used as a time base generator to provide a stable reference frequency to data synchronizers. Once data synchronizers achieve lock using the stable reference frequency and switch over to read data, the time base generator PLL is switched over to function as a data synchronizer PLL in a read mode. Thus, one of the PLLs is used as both time base generator and data synchronizer PLL, thereby eliminating the need for extra PLL circuitry and requiring only two PLL circuits to support time base generation and data synchronization.

摘要： A reflector 3 having a bottom section 4 and a slope section 13 surrounding the periphery of the bottom section 4 is provided, and an LED 5 is mounted on the center of the bottom section 4. A holder section 9 of a light control means 7 is detachably mounted to cover a lens 6 of the LED 5, while a circular plate section 18 of the light control means 7 is provided with a main reflecting section 11 and a reflecting transmission section 12. The main reflecting section 11 is designed to reduce the transmission amount from the LED 5, thereby causing most of the light to reflect on the reflector 3 side. On the other hand, the reflecting transmission section 12 permits a larger amount of transmission than in the main reflecting section 11. In this manner, it is possible to realize substantially uniform brightness in the entire upper section of the reflector 3 by the light transmitted through the main reflecting section 11 and the reflecting transmission section 12 and the light diffusely reflected from the reflector 3.
