  • Publication number: 20050268130
    Abstract: It is aimed at providing a data processor capable of suppressing a sudden current change from the viewpoint of a synchronization clock. A data processor 1 comprises a clock pulse generation circuit and a circuit module operating on input clock signal CLKi output from the clock pulse generation circuit. In case of restoration from a power-on reset period or a standby state, the clock pulse generation circuit stepwise changes frequencies of the clock signal from low to high frequencies. This makes it possible to prevent a power supply current from suddenly increasing in case of restoration from the power-on reset period or the standby state.

  • Patent number: 5579291
    Abstract: A magneto-optical head apparatus of a recording and/or reproducing apparatus includes a light beam generating unit, an objective lens, a separating optical element, a reflecting mirror, and a photodetector. The objective lens converges a light beam emitted from the light beam generating unit on a point on an optical axis, e.g., a point on the recording layer of a magneto-optical recording medium. The separating optical element deflects the light beam emitted from the light beam generating unit, and separates the light beam emitted from the light beam generating unit and a light beam through the objective lens. The reflecting mirror deflects the light beam emitted from the light beam generating unit and deflected by the separating optical element at 90.degree. so that the light beam is led to the objective lens. The photodetector receives the light beam irradiating through the objective lens and passing through the separating optical element.
