    摘要： A converter that records or reproduces information to or from a recording medium while making a movement relative to the recording medium is mounted on a slider. The slider has at least a pair of openings on a side face thereof, and airflow generated by the movement relative to the recording medium flows in via one of the paired openings, passes in a vicinity of a surface of the converter other than a surface thereof facing the recording medium, and thereafter flows out via the other one of the paired openings. With this, the ability to cool the converter is improved.

    摘要： A magnetic head device comprises a moving member comprising a slider, which is fastened to a system for applying a magnetic field and slides on or is close to an optomagnetic disk, an elastically supporting member having a first end, to which the moving member is attached, the elastically supporting member supporting the moving member in a manner that the moving member can move, a fastening member fastened to a second end of said elastically supporting member, a position control pin, and a position control hole formed at the center of gravity of the moving member. When a shock is applied, the position control pin mates with the position control hole, so that not only the vertical position of the moving member, but also its horizontal position can be restricted. Moreover, since the position control hole is formed at the center of gravity of the moving member, a resultant moment on the moving member can be avoided. Thus, a magnetic head device with excellent shock resistance can be provided. Since it is not necessary to provide a weight extending the moving member in longitudinal direction, further miniaturization of the device can be realized.

    摘要： A magneto-optical head includes an optical head provided with a light-focusing device for focusing a beam spot on an information-recording medium and a magnetic head provided with a magnetic-field applying device for applying a magnetic field to the information-recording medium. The optical head and the magnetic head have the same rotation center and are arranged to rotate together in respective planes parallel to the information-recording medium.The relative position shift between the beam spot and the magnetic-field applying device, which occurs when the beam spot follows eccentric components of the information-recording medium, is avoided. As a result, a magnetic-field applying device can be miniaturized, resulting in decrease in power consumption and in inductance of the magnetic head. Consequently, data can be recorded at a high frequency, thus improving the recording density and transfer speed.

    摘要： A magnetic head is configured so that an aspect ratio w0/h0 of a cross section of a coil (11) is set to be 1 to 4, or preferably, approximately 1.5. This configuration suppresses the heat generation in the magnetic head that performs the magnetic field modulation, without impairing the efficiency, thereby making the magnetic head suitable for high-frequency modulation.

    摘要： A head main body (12) is supported at a free end of a cantilevered suspension (14). The head main body (12) has a first holding portion (5) that is substantially in parallel to an information recording medium (1), and the suspension (14) has a second holding portion (6) that is substantially in parallel to the information recording medium (1) and is located near the free end of the suspension (14). When a magnetic head device is not used, the head main body (12) is spaced away from the information recording medium (1). At this time, when an external shock is applied, the first holding portion (5) and the second holding portion (6) contact each other, thereby preventing a permanent deformation of the suspension (14). It is possible to reduce a displacement amount against a shock when the head main body (12) is spaced away from the information recording medium (1). Consequently, a spacing amount of the magnetic head main body (12) can be reduced. As a result, it becomes possible to make a thinner optomagnetic recording/reproducing apparatus.

    摘要： A slider portion is provided with protrusion portions having a spherical surface, contacting a recording medium. A center of a magnetic pole is arranged on the line C1 connecting the vertices of the protrusion portions. Line C1 is more or less aligned with the gliding direction of the protrusion portions. Thereby, positional variations between the magnetic pole and the surface of the recording medium can be minimized even when the head slider is tilted with respect to the surface of the recording medium. Thus, a gliding converter support structure is provided whose conversion efficiency does not decrease when it is tilted with respect to the surface of the recording medium, which is easy to manufacture, has little gliding resistance, and does not easily accumulate dust.
