摘要： A light receiving circuit (114) includes a light inputting circuit (113) which converts one-system optical signal to be outputted from an optical transmission path (101) to an electrical signal and inverts a potential of the electrical signal each time the optical signal is detected, and a buffer circuit (110) which amplifies the electrical signal converted by the light inputting circuit and outputs the same. According to such configuration, since one-system optical signal may be inputted to the light receiving circuit, a system circuit configuration can be avoided to be complicated.

摘要： An MR head in which a spin-valve device unit is formed into a horizontal shape and an anti-ferromagnetic layer is not required, is provided. The spin-valve device unit includes a first ferromagnetic layer, one and another permanent magnetic layers arranged on both end portions of the first ferromagnetic layer and creating a magnetic path from one of the end portions of the first ferromagnetic layer toward the other thereof. A second ferromagnetic layer is provided above the first ferromagnetic layer through a non-magnetic conductive layer and a soft magnetic layer is provided above the second ferromagnetic layer through a non-magnetic layer. The both end portions of the second ferromagnetic layer are designed to contact with outer end portions of the permanent magnet layers, respectively. Surfaces of the permanent magnet layers are perpendicular to the surface of a magnetic storage medium and to the magnetization direction thereof.

摘要： A thin film magnetic head has individual coils series-connected to one another and formed with three connecting terminals selectively connectable to an external driver to effect magnetic reading and writing operation. The magnetic head has 2n (n being an integer of not less than 1) spiral patterns formed by a selective plating method, n spiral patterns out of the 2n spiral patterns being connected in series so that a first connecting terminal and an intermediate connecting terminal are formed to thus give a first coil, the remaining n spiral patterns out of the 2n spiral patterns being connected in series so that one end thereof is connected to the intermediate connecting terminal and the other end serves as a second connecting terminal to thus give a second coil, wherein the 2n spiral patterns are formed on n layers and each layer has two spiral patterns, one of which is a component of the first coil and the other of which is a component of the second coil.
