摘要： A magnetic head includes a coil (3) for generating a magnetic field, and an electroconductive film (5) superposed over the coil (3) so as to be electrically insulated from the coil (3). The film (5) is formed with a center hole (50). The film (5), composed of a non-magnetic substance, is provided with a first slit (51) extending from the hole (50) to the outer peripheral edge of the film (5). A second slit (52) surrounds the inner edge (5a) of the film (5). The inner edge (5a) and outer doughnut-like portion are connected to each other by continuity components (5c).

摘要： A magneto-optical head device includes a light source (1), an objective lens (5) which condenses a light beam emitted from the light source (1), an auxiliary lens (6) which converts an effective numerical aperture of the light beam condensed by the objective lens (5) to irradiate a recording medium (8) with the light beam, and a magnetic reproducing head (7, 72) which is integrated into the auxiliary lens (6). The magneto-optical head device can thus be decreased in size and information can be reproduced from both surfaces of a disk since the magnetic reproducing head (7, 72) is integrated into the auxiliary lens (6). Further, when a thermomagnetic recording medium is employed as the recording medium (8), the magneto-optical head device can reproduce information recorded at a high track density and a high line density.

摘要： A magnetic head unit (1) is provided in which the distance (L) between a surface of the gimbal plate (4) put touching the pressing member (52) and a surface of the magnetic head (5) facing the first or second disc-shaped recording medium is set to fall in a range of 0.3 to 0.8 mm and thus the coil winding cavity (14) can be formed in the intermediate portion of the magnetic head (5) in the direction of the head thickness and the magnetic heads (5) can be kept stably in place in relation to the disc-shaped recording medium. Also, a recording and/or reproducing apparatus (60) using the magnetic head unit is provided.

摘要： A thin film helical conductor coil assembly (110) includes an electrically-nonconducting ceramic substrate (204) having a substantially planar surface and separated first and second magnetic elements (112,116) which mutually bound a volume of the ceramic substrate (204). The thin film conductor coil assembly also includes a thin film magnetic core (256), which magnetically connects the first magnetic element to the second magnetic element. The thin film magnetic core(256), which overlies the substantially planar surface of the ceramic substrate (204), is constructed from a compliant electroplated magnetic material. The thin film conductor coil assembly further includes an electroplated thin film helical coil (210) which traverses about the thin film magnetic core (256) and forms a conductive path from a first terminal (264) to a second terminal (264).
