    摘要: A magnetic recording medium with a high recording density has a first ferromagnetic layer, a non-magnetic layer, and a second ferromagnetic layer successively deposited as the recording layer on a non-magnetic substrate. The recording layer is heated in concentric circular shapes to divide it into regions in which the magnetic interactions between the ferromagnetic layers exhibit ferromagnetism and regions that exhibit anti-ferromagnetism. The ferromagnetic regions are used for recording tracks, and the anti-ferromagnetic regions function as guard bands. In this manner track density is increased without roughening the surface of the recording medium.

    摘要: An influence by a vibration which is transmitted in the air is reduced, thereby preventing an erroneous detection of coordinates or a deterioration in a detecting precision. An elastic resin sheet is arranged on a coordinates input surface side of a vibration transmission plate so as to have a gap between the resin sheet and the vibration transmission plate and is fixed by an adhesive layer. When coordinates are inputted by a vibrator pen, namely, when a vibration is inputted, the resin sheet is warped by a writing pressure of the vibrator pen and the resin sheet comes into contact with the vibration transmission plate. Therefore, the vibration applied by the vibrator pen is efficiently transmitted to the vibration transmission plate. On the other hand, a vibration transmitted from the air is reflected by the boundary on both surface sides of the resin sheet and by the surface of the vibration transmission plate by a difference between acoustic impedances, so that the vibration entering the vibration transmission plate is remarkably reduced.

    摘要: A plurality of test pieces are taken from a long-sized substrate made of stainless steel, where the test pieces are arranged in parallel to the width direction TD of the substrate in a region near the forward end of the substrate. A variation among the curvatures of the test pieces is then measured. A substrate where the variation in the curvature is 0.002 [1/mm] or smaller is selected as a substrate used in manufacture of magnetic head suspensions. While the selected substrate is transported in its length direction, an insulating layer and a conductor layer are stacked on the substrate to form a plurality of magnetic head suspensions.

    摘要: A coordinates input apparatus which detects vibration, inputted by a vibration-input pen, by a plurality of vibration sensors provided on a vibration-transmitting tablet, and derives coordinates of a vibration-input point based on vibration transmitting time on the vibration-transmitting tablet. The vibration-transmitting tablet comprises a glass substrate and two sheets of resinous film laminated on the glass substrate. The two sheets of resinous film are laminated on both surfaces of the glass substrate in an orientation such that the stretched directions of the resinous film differ for 90 degrees. By this, a vibration-transmitting tablet where sheets of protection film are laminated, and a coordinates input apparatus which minimizes the changes in vibration propagation velocity depending on the propagation directions, are realized.
