摘要： A pickup for a magneto-optical recording medium is provided, which improves quality of reproduced signals by eliminating a phase difference between the polarizations and is capable of coping with magneto-optical recording media of different recording/reproducing systems. A return light beam of light reflected by a magneto-optical recording medium is polarized and separated into ± first-order diffracted lights through a light-branching diffraction element provided between a light source and an objective lens. The ± first-order diffracted lights are compensated for their phases through first and second phase compensation elements so that there is no phase difference between the polarizations, and are, further, polarized and separated through the first and second polarization/separation elements, and are received by first and second light detectors. Use of the first and second phase compensation elements having different phase compensation amounts makes it possible to cope with the magneto-optical recording media of different recording/reproducing systems.

摘要： First, a recording magnetic field is generated by a magnetic head using a coil drive current a.sub.1, and a first data signal is recorded on a groove of a recording layer of a magneto-optical disk. Thereafter, similarly, a second data signal is recorded on the same groove as above by a coil drive current a.sub.2. In this case, the first and second data signals have different signal frequencies which do not overlap each other. The amplitude A.sub.1 of the coil drive current a.sub.1, is set greater than the amplitude A.sub.2 of the coil drive current a.sub.2. This arrangement permits multiple recording and increases the recording capacity of the magneto-optical disk.

摘要： An information reproducing apparatus which has a rotating driver for rotating a disc-shaped recording medium, a floating-type head for reproducing information recorded in the recording medium while floating above the disc-shaped recording medium that is being rotated by the rotating driver, and a suspension, made of an elastic member, for supporting the floating-type head. The information reproducing apparatus is characterized in that the floating-type head has a slider which is floated by an air flow that is directed near the surface of the rotating disc-shaped recording medium, and that the slider has a bevelled portion at one side that faces the outer edge of the disc-shaped recording medium such that any contact between the slider and the ridge that exists along the outer edge area of the disc-shaped recording medium is virtually eliminated. Since the slider is virtually free from contacting the ridge that exists along the outer edge area of the disc-shaped recording medium, the storage capacity of the disc-shaped recording medium can be more effectively used.
摘要翻译：一种具有用于旋转盘形记录介质的旋转驱动器的信息再现装置，用于在浮动在由旋转驱动器旋转的盘形记录介质上方的同时再现记录在记录介质中的信息的浮动型头;以及由弹性构件制成的用于支撑浮动头的悬架。信息重放装置的特征在于，浮动式头部具有滑块，该滑块由朝向旋转的盘形记录介质的表面的空气流浮动，并且滑块在一侧具有倾斜部分，面对盘状记录介质的外边缘，从而实质上消除了沿盘形记录介质的外边缘区域存在的滑块和凸脊之间的任何接触。由于滑块实际上没有接触沿着盘形记录介质的外边缘区域存在的脊，所以可以更有效地使用盘形记录介质的存储容量。

摘要： A photomagnetic composite head comprising a magnetic head and an optical head that are integrated into one unit, an optical waveguide path of the optical head being located in the surface of the magnetic head that faces a recording medium, and a laser beam that passes through the optical waveguide path being irradiated on a point on the recording medium where a magnetic field is impressed from the magnetic head, whereby recording can be performed under a condition in which the coercivity of the recording medium has been lowered by the laser beam, thus making it possible to achieve high density recording by using a recording medium with a high coercivity.

摘要： In view of achieving a cost reduction of an antenna switch, a technique is provided which can reduce harmonic distortion generated in the antenna switch as much as possible in particular even when the antenna switch is comprised of a field effect transistor formed over a silicon substrate.Each of a TX series transistor, an RX series transistor, and an RX shunt transistor is comprised of a low voltage MISFET, while a TX shunt transistor is comprised of a high voltage MISFET. Thus, by reducing the number of serial connections of the high voltage MISFETs constituting the TX shunt transistor, the nonuniformity of the voltage amplitudes applied to the respective serially-coupled high voltage MISFETs is suppressed. As a result, the generation of high-order harmonics can be suppressed.
