摘要： PURPOSE:To bring a magnetic gap into contact with a disc efficiently to obtain high adhesiveness by curving the sliding surfaces of the 1st leg parts of a pair of magnetic heads so as to be projected slightly higher than the slinding surfaces of the 2nd leg parts. CONSTITUTION:A recording/reproducing core 3 and an erasing core 4 are embedded in the disc sliding surface 6a of the 1st led part 6 of a core holding part 2 of one magnetic head 1 and the shape of the sliding surface is curved so as to be projected slightly higher than the sliding surface 7a of the 2nd leg part 7. The other magnetic head 10 is similarly constituted. A floppy disc 9 is held between the magnetic heads 1, 10 to execute recording/reproducing. When the adhering pressure of both the heads 1, 10 are increased under said status, efficient contact state is obtained without the generation of a specific trouble for the contact and high adhesiveness can be attained between a gap 3a and the floppy disc 9.

摘要： PURPOSE:To assure an excellent magnetic characteristic by positioning the sliding surface of a substrate which supports a thin ferromagnetic metallic film toward the (1, 1, 0) face from the single crystal manganese-zinc ferrite face and toward the (2, 1, 1) face from the (1, 1, 1) face respectively within specific angles of inclination. CONSTITUTION:A magnetic head is manufactured by using respectively single crystal manganese-zinc ferrite as the core substrate and an amorphous alloy of cobalt-niobium-zirconium as the thin ferromagnetic metallic film. The magnetic head is brought into contact with a magnetic disk while the disk is kept rotated to maintain the continuous sliding contact between the head and disk. As a result, the head is so formed that the sliding surface of the core substrate is positioned within the range of 0-30 angle of inclination from the (1, 1, 1) face toward the (1, 1, 0) face and within the range of 0-30 angle of inclination from the (1, 1, 1) face toward (2, 1, 1) face, then the core substrate and the thin ferromagnetic metallic film wear approximately at the similar rate and therefore the difference of steps between both is extremely small.

摘要： PURPOSE:To attain efficient contact state and high adhesiveness by forming the area of the sliding surface of the 1st leg part of a magnetic head smaller than that of the 2nd leg part and opposing the 1st leg part of one magnetic head to the center of the 2nd leg part of the other magnetic head at the holding of a disc. CONSTITUTION:The 1st magnetic head 2 consists of the 1st narrow leg part 7 having a recording/reproducing core or the like and the 2nd wide leg part 8 and the 2nd magnetic head 3 is similarly constituted. When a both-side floppy disc 1 is held between both the heads 2, 3, the 1st leg part 7 of the head 2 is opposed to the approximate center of the 2nd leg part 8. Since the area of the 1st leg part 7 is formed smaller than that of the 2nd leg part, the pressure of the contact surface can be increased and the adhesiveness can be also increased. In addition, the 1st leg part 7 is opposed to the center of the 2nd leg part 8, so that the contact surfaces are not hurt and the efficient contact state can be kept even if the disc 1 is warped.

摘要： PURPOSE:To attain stable press contact between a disc and a head by making the length of a coil winding window of an erasure head sufficiently longer than that of the winding window of a recording/reproducing head and winding a coil at the bottom so as to decrease the distance between a head face and a gimbal. CONSTITUTION:The coil winding window 5a of the recording/reproducing head core 1 is minimized taking the recording reproducing efficiency into account and provided in contact with the head 1a. Then a coil winding window 5b of an erasure head core 4 is made sufficiently longer than the winding window of the recording/reproducing head core 1 and an erasure coil 7 is wound at the bottom. Thus, the thickness of the slider 4 is made thin and the distance between a face of the gimbal 6 and the head front face is decreased, then stable press contact between the disc and the head is attained to improve the tracking.

摘要： PURPOSE:To improve the adhesion of a magnetic core to a disc by decreasing the length of head elements arranged opposedly vertically while clipping the disc to be shorter than the length of the element holder so as to improve the contact surface pressure. CONSTITUTION:The length L1 of the head elements 3 of the magnetic head device arranged opposedly vertically while clipping a floppy disc in the disc running direction is decreased than the length L2 of the head element holder 2. since the area of the sliding faces 4a, 5a of the head element 3 is decreased remarkably to the area of the sliding face 2a of the holder 2, the contact surface pressure of the sliding faces 4a, 5a is increased in applying a pressing force to the head device. Thus, the adhesion with the disc is improved by increasing the contact surface pressure of the head without increasing the total surface pressure so as to improve the recording/reproducing characteristic.
摘要翻译：目的：通过减少磁头元件相对垂直设置的头部元件的长度，同时将磁片限制在比元件保持器的长度短，从而提高接触表面压力，从而提高磁芯与磁盘的密合性。构成：在盘驱动方向上夹住软盘的同时相对垂直设置的磁头装置的头元件3的长度L1比头元件保持架2的长度L2减小。由于滑动面4a，头元件3的5a相对于保持器2的滑动面2a的面积显着减小，因此在向头部装置施加按压力的同时，滑动面4a，5a的接触面压力增加。因此，通过在不增加总表面压力的情况下增加头部的接触表面压力来提高与盘的粘附性，从而提高记录/再现特性。
