    摘要： A separation type optical head according to the present invention includes at least a light source portion for emitting collimated beams, a focusing device (a focusing lens) for focusing the collimated beams onto an information recording surface of an optical disc medium, a focal point control mechanism for the position of the spot on the information recording surface, and a photo-detection portion for receiving beams reflected by the information recording surface. The structure is divided into a fixed portion including the light source portion and the photo-detection portion and a movable portion including the focusing device (focusing lens) and the focal point control mechanism. At least the movable portion of the separation type optical head is movably accommodated n a frame (sealing case) for the optical head so as to prevent irregular vibrations of the movable portion due to high speed air flows or turbulence. Furthermore, a focal point control mechanism of an air float type may be employed in the movable portion of the separation type optical head so as to actively utilize the high speed air flow generated due to the rotation of the disc medium to perform a rough adjustment of the focal point of the focusing device.

    摘要： A thin film magnetic head has a first magnetic core member carried by a substrate, a gap layer formed on the first magnetic core member, and a second magnetic core member formed in a spaced relation with the first magnetic core member. The second magnetic core member is coupled to the first magnetic core member to form a magnetic path and to have an end portion of the gap layer sandwiched by gap defining portions of the first and second magnetic core members. A coil conductor is wound about the magnetic path. In one embodiment, the first magnetic core member includes a first magnetic layer made of a magnetic material having stable magnetic properties during heat treatment and the second magnetic core member includes a second magnetic layer made of a material having a saturation flux density higher than that of the material of the first magnetic core member.

    摘要： Disclosed is a thin film magnetic head having a structure wherein the main portion of a coil consists of a copper or copper alloy layer and its upper surface is covered with a thin film mask consisting of titanium, titanium oxide, chromium and/or chromium oxide. The magnetic head of the invention can prevent the occurrence of projecting etching residues at the upper edge portion of the coil and can easily increase the cross-sectional area and the winding density of the coil. Furthermore, when the thin film mask consists of titanium and/or titanium oxide, a titanium diffusion prevention film consisting of chromium, for example, is interposed between the thin film mask and the copper or copper alloy, so that the resistance change of the coil scarcely takes place owing to heat treatment in a production process after the formation of the coil and the head reliability can be further improved.
