摘要： A bias conductor layer for a bias current path extends through the gaps of a plurality of unit thin-film magnetic heads, which are placed side by side over signal conductor layers. A spacer layer is provided between upper and lower magnetic material layers and extends over the area including the gaps formed between the bias conductor layer and the signal conductor layers, and an additional thickness of spacer material is provided at the gaps so that the distance between the upper and lower magnetic material layers is increased and therefore magnetic short-circuiting is avoided.

摘要： This invention provides a light absorber which can be used for optical equipment like optical-disk equipment and a liquid crystal display. The light absorber has a layered structure including a light absorbing layer and a transparent layer. The light absorbing layer absorbs a reflected light from the inside of the absorber as well as incident light into the absorber while the transparent layer helps attenuate the reflected light by interference of light. One of the light absorbing layers which is thicker than others may work as a shading layer for the incident light.

摘要： A head cleaner for a magnetic recording and/or reproducing apparatus for cleaning rotary magnetic heads. The head cleaner includes a rotary spindle rotatably mounted on a support arm movable between an operative position, in which the head cleaner is in position to clean the magnetic heads, and an inoperative position separated from the magnetic heads. The head cleaner also includes a plurality of oblong webs of non-woven fabric with or without an abrasive material coated on one surface thereof. The oblong webs of non-woven fabric are fixedly secured to the rotary spindle so as to extend radially outwardly therefrom while being spaced an equal distance from each other in a direction circumferentially thereof.

摘要： A head cleaning device for use in a magnetic recording and reproducing apparatus comprises a cleaning roller in which a lubricant with an excellent lubricating action under low humidity conditions impregnates the soft material. This lubricant compensates for the drop in the natural lubricating action resulting from a moisture deficiency, and therefore prevents the production of seized deposits. Furthermore, the head cleaning device comprises a first cleaning portion impregnated with polymer resin and abrasive particles, and a second cleaning portion comprising only a soft material, the second cleaning portion can remove by wiping any abrasive particles or deposits left on the magnetic head surface immediately after the abrasive cleaning action of the first cleaning member.

摘要： A magnetic head and a production method therefore in which permanent magnet films for applying a DC bias magnetic field Hd h to a magnetoresistive effect element film (MR element film) is arranged on both sides of the thickness dimension of the MR element film through at least a non-magnetic film therebetween. In making the MR element film thicker in order to reduce distortion, the DC bias magnetic field Hd b to be applied to the MR element film is also required to be increased. Unlike the prior art in which the above-mentioned requirement is met by increasing the thickness of the permanent magnet film under the thickness of the MR element film resulting in the problem of breakage of a film member above or under the thickness of the permanent magnet film, the invention further comprises a second permanent magnet film above the thickness of the MR element film without increasing the thickness of the first permanent magnet film. In the case of a magnetic head with a shield members of soft magnetic material holding the MR element film from both sides of the thickness thereof, the MR element film is made thicker to make reproduction possible without any distortion or without substantially increasing the gap. For this purpose, the MR element film is held on the sides above and under the thickness thereof by first and second permanent magnet films which in turn are held by the shield members. To minimize distribution of the MR element film, a comparatively high-temperature process after forming of the MR element film i.e., forming of the second permanent magnet film is effected at optimum temperature, and a magnetic field is applied along the magnetic easy axis of the MR element film.
