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).

摘要： A magnetic head core for a magnetic head including first and second ferrite members (12,14) butted and bonded together to form an annular, closed magnetic path around a coil-winding groove (16), and a coil attached to a coil-winding portion (30) of the first ferrite member. The first and second ferrite members provide a sliding surface (22) to which a magnetic recording medium is opposed, and which extends across the first and second ferrite members. A non-magnetic material (32) is secured to at least one of an inner surface and an outer surface of the coil-winding portion (30). The non-magnetic material is located below the sliding surface, and is spaced apart from the magnetic recording medium with the sliding surface disposed between the non-magnetic material and the magnetic recording medium. Low inductance can be achieved, combined with high mechanical strength.
