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.
摘要翻译：目的：通过将磁头的第一腿部的滑动面的面积比第二腿部的面积小，并且将一个磁头的第一腿部与第一腿部的第一腿部相对的方向，形成有效的接触状态和高粘接性另一个磁头的第二个腿部分在一个光盘的保持下。构成：第一磁头2由具有记录/再现芯等的第一窄腿部分7和类似地构成第二宽腿部分8和第二磁头3组成。当双面软盘1被保持在两个头部2,3之间时，头部2的第一腿部7与第二腿部8的大致中心相对。由于第一腿部7的面积是形成为小于第二腿部的形状，可以提高接触面的压力，并且还可以提高粘接性。此外，第一腿部7与第二腿部8的中心相对，使得接触表面不受伤，并且即使盘1翘曲也可以保持有效的接触状态。

摘要： PURPOSE:To attain always a good head touch by providing a head sliding member where a taper face inclined with respect to the recording face of a magnetic sheet is formed on the side face. CONSTITUTION:A taper face 51 whose one end is close to a magnetic sheet 31 and the other end is inclined to get away gradually from the recording face of the magnetic sheet 31 is formed on the side face, which faces the recording face of the magnetic sheet, of a base body consisting of a rigid body of a nonmagnetic metal or the like of a head sliding member 33, and a space 52 where a magnetic head 32 is set is provided in the center part. When the magnetic sheet 31 is rotated and driven in a high speed, a negative pressure is generated between the taper face 51 and the magnetic sheet 31 by an air flow accompanied with rotation. The magnetic sheet 31 is attracted to the taper face 51 and is bent by the negative pressure. Thus, the magnetic sheet 31 is stably brought into contact with the front end part of the magnetic head 32.

摘要： PURPOSE:To stabilize the revolution of a rigid drum by forming a dynamic pressure air bearing within a microgap between the cylinder part of the rigid drum and a revolution driver part in a high-speed revolution mode. CONSTITUTION:When a motor shaft 37 is revolved after a motor 36 is driven, a magnetic drum 13 is revolved clockwise at a high speed. At the same time, the rotary phase of the drum 13 is detected by a rotary pulse pickup head 41. Thus the air within a circular gap between the drum 13 and an inside cartridge holder 35 flows toward an arrow mark. Therefore a dynamic pressure air bearing 42 is formed between the inside of the drum 13 and the holder 35 over the entire length of the lengthwise direction and over the entire circumference of the drum 13. The drum 13 changes its position in the direction where the core deflection of the drum 13 is compensated centering the connected part with the shaft 37. Finally the drum 13 is revolved with

摘要： PURPOSE:To reduce output modulation and to prolong the life of a floppy disk by setting the abutting position of a pivot backward from the center of a magnetic head. CONSTITUTION:The position of a support pin 21 is set backward from the center point of the magnetic head 20 and a contact force point is set at the intersection O of the center line of the magnetic head 20 and the contacting surface of a medium. When the support pin 21 is shift backward from the center of the magnetic head 20, distance (l) is l=Htantheta, tantheta=F/W, and F=Hmu, so l=Hmu. Namely, when the position where the support pin 21 presses the magnetic head 20 is shifted backward from the center of the magnetic head by muH, the magnetic head surface applies uniform surface pressure to the medium; the life of the medium is prolonged and the output modulation is reduced, thereby reducing errors in recording and reproduction. In said equations, theta is the angle of composite force N, H is the height of the magnetic head from the contact surface of the medium to the lower end of the support pin, and mu is the coefficient dynamical friction between the magnetic head and medium.
