Abstract: When a circuit that is likely to cause noise is enabled, a control circuit turns on a switch so that an inverter will be formed by one P-channel MOSFET and two parallel-connected N-channel MOSFETs. This helps enhance the current capacity of the inverter on its N-channel MOSFET side, and thereby lower the threshold voltage of the inverter.

Abstract: In an outer rotor type spindle motor in which a shaft 2 and a stator 3 are supported by and fixed to a flange 1, damping members 4 and 5 are interposed between the flange 1 and the stator 3 and between the flange 1 and the shaft 2, or the flange 1 itself is formed of a damping material. Thus, electromagnetic vibration from the stator 3 or rotating vibration from the shaft 2 are damped and absorbed by the damping members 4 and 5. Accordingly, the generation of vibration or noise in the flange can be prevented which is caused by the transmission of the electromagnetic vibration generated on the stator due to an alternating current supplied to a stator coil or by the transmission of the rotating vibration of a rotor received by the shaft to the flange.

Abstract: This invention relates to magneto-optical recording media such as magneto-optical disks and cards, manufacturing methods of the medium and a magneto-optical recording and playback device to record and play back data using the magnetic-optical recording media. The magneto-optical recording medium has a recording layer and a reflective layer on a substrate, and the recording layer has a layered structure in which at least on spinel ferrite (or rutile-type oxide or hematite) layer and at least one garnet ferrite layer are piled together.

In the magneto-optical recording and playback device to record and playback data, the wavelength of light for recording data is different from that for reading data, which is preferable for a magneto-optical recording medium comprising a garnet ferrite layer.

Abstract: A method and an apparatus of inspecting the surface of a wafer, where two or more kinds of laser are switched or mixed to make the laser incident on the film-coated wafer by a same incident angle, in which inspection data regarding an inspection apparatus and film parameters regarding a film are stored in storage means of the inspection apparatus in an associated state with each other so as to obtain predetermined inspection conditions. When performing each measurement, an operator sets the film parameters of the wafer to be measured by setting means of the inspection apparatus. Thus, desired inspection conditions are automatically set in the inspection apparatus. The film parameters that the operator sets at each measurement are a film thickness and a film refraction index.
