摘要： PURPOSE:To improve a reliability of a device by providing two control means for controlling a movement in a normal direction of a disk at two positions in a radial direction of the magnetic disk. CONSTITUTION:At an innermost circumferential side end section of a groove section 3a of a pad plate 3 with respect to a disk 2 non-cut a section 3c is disposed. When such shape pad plate 3 is used, the disk 2 constantly contacts the non-cut section 3c of the groove of the pad plate 3 at a point 3c and a position of the disk 2 in a direction of a rotating axis is always constant, even when a change is generated at a center part of the rotation, at a point 2c. therefore, an influence is small to an abutting section 2b of a head 1 and the disk 2, and a characteristic of a good recording and reproduction can be stably maintained.

摘要： PURPOSE:To release a floppy disk from an attracted condition so as to eliminate the necessity of the loading and unloading device of a magnetic head and miniaturize a magnetic disk driving device, by providing a play to the power transmitting system between a driving motor and magnetic disk and rotating the driving motor in the normal direction after rotating it in the opposite direction. CONSTITUTION:A play of an angle of about 30 deg. exists between a drive hole 5 and drive pin 9 in the rotating direction. When a driving signal is given to a terminal 17 or a normally rotating signal, for example, 'H' is given to another terminal 18, a motor driving circuit 16 rotates a motor 7 in the normal direction. When a reversely rotating signal 'L' is given, the circuit 16 rotates the motor 7 in the reverse direction. When the rotation is shifted from reverse to normal even if magnetic heads 13 and 14 are attracted by a floppy disk 1, the rotating speed of the disk 1 is increased and the drive pin 9 gives such an impact as is received when beaten with a hammer to the disk 1, since no load is applied until the pin 9 hits the drive hole 5. Therefore, the disk 1 can be released from the attracted condition.
摘要翻译：目的：为了从被吸引的状态释放软盘，为了消除磁头的装载和卸载装置的必要性，使磁盘驱动装置小型化，通过在驱动电动机和磁铁之间向动力传递系统提供游戏并且沿相反方向旋转驱动电动机沿正常方向旋转。构成：角度约30度的游戏在驱动孔5和驱动销9之间沿旋转方向存在。当向终端17或正常旋转信号提供驱动信号时，例如，向另一个端子18提供“H”，马达驱动电路16使马达7沿法线方向旋转。当给出反向旋转信号“L”时，电路16使电机7反向旋转。当磁头13和14被软盘1吸引时，当旋转被反向移动到正常时，盘1的旋转速度增加，并且驱动销9产生如以锤子殴打时所受到的冲击由于在引脚9撞击驱动孔5之前没有施加负载。因此，可以将盘1从吸引的状态释放。

摘要： PURPOSE:To attain always a good head touch by constituting a magnetic head sliding member with the first and the second members having taper faces which are inclined with respect to the recording face of a magnetic sheet. CONSTITUTION:A head sliding member 33 consists of the first and the second members 51 and 52 of nonmagnetic metallic rigid bodies, and one end of each of respective taper faces 41 and 42 is close to a magnetic sheet 31, and the other end is inclined in such direction that it gets away gradually from the recording face of the magnetic sheet 31. A magnetic head 32 is inserted in a gap 34 between members 51 and 52. When the magnetic sheet is rotated and driven in a high speed, a negative pressure is generated between taper faces 41 and 42 and the magnetic sheet 31 by an air flow accompanied with rotation, and the magnetic sheet 31 is attracted to the side of the taper face 41 and is bent by this 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 attain excellent and stable head contact in case of recording/ reproduction by providing a regulating plate so as to be contacted at the rear face of a magnetic recording medium and setting the regulated level so as to be projected toward the magnetic head more than unregulated level of a recording face.
CONSTITUTION: The relative level of a regulated plate 32 to a magnetic sheet 14 is set in the level of a recording face 22 of the magnetic sheet 14 so that the level of the recording face 22 of a part having the regulated plate 32 is positioned lower in comparison with the level of the recording face 22 of a part not controlled by the regulated plate 32. A magnetic head 30 is projected to a part on which recording or reproduction is attained on the magnetic sheet 14, the pressing force of the head 14 deforms partially the sheet 14 toward the inside of the recessed part 36 and the sheet 14 rotated in the direction of the arrow B is slid with a guide face 38. The effect of curl or the like to a recording signal is eliminated by projecting the regulated level 62 of the magnetic sheet 14 toward the head 30 more than the unregulated level 60.

摘要： PURPOSE:To suppress face deflection of a medium and to obtain stable contact pressure by providing incorporatedly the 1st pad member to a magnetic head before and after the magnetic head along the running direction of the magnetic recording medium and providing the 2nd pad member with press contact onto a position opposite to the other side face. CONSTITUTION:Since the medium is clipped with a couple of pad members 13A, 13B and other couple of pad members 14A, 14B at a position before and after a magnetic head 11 along the rotating direction of a disc 2 being the medium running direction, the face deflection of the medium near the magnetic head 11 is suppressed effectively. Since the amount (d) of projection of a tip of the magnetic head 11 to a medium recording face 2a is set by the amount of head projection from a medium contact face of the pad members 13A, 13B, a high mechanical accuracy is attained and the head contact pressure is also set with high accuracy. Even if the clipping force of the medium by the pad members 13A, 13B and 14A, 14B is set to a value suppressing sufficiently the face deflection, since no direct application of pressing force to the magnetic head 11 exists, the head contact pressure is not increased and damages to the medium and the head are prevented.
摘要翻译：目的：为了抑制介质的面部偏转并且通过在磁头沿着磁记录介质的运行方向之前和之后提供第一衬垫构件到第一衬垫构件以获得稳定的接触压力，并且为第二衬垫构件提供压接到与另一侧面相对的位置。构成：由于介质在沿着作为介质运行方向的盘2的旋转方向的磁头11之前和之后的位置处夹有几个衬垫构件13A，13B和其它一对衬垫构件14A，14B，有效地抑制了磁头11附近的介质的面偏转。由于磁头11的尖端向介质记录面2a突出的量（d）是通过从衬垫构件13A，13B的介质接触面的头部突起的量来设定的，所以获得了高的机械精度，头部接触压力也以高精度设定。即使由衬垫构件13A，13B和14A，14B将介质的夹持力设定为充分抑制面部偏转的值，由于不存在对磁头11的直接施加按压力，所以头部接触压力不是防止对介质和头部的增加和损坏。

摘要： PURPOSE:To suppress the amplitude of vibration mode which occurs to a floppy disk in different position to a constant small level at a position close to a magnetic head, and to stabilize writing and reading operation by varying pressure according to the position on a jacket. CONSTITUTION:A floppy disk presser 2 is provided close to a read/write window 1. This floppy disk presser 2 consists of a pressing plate 4 and springs 7, which have different spring constants K1-Kn. Consequently, the floppy disk presser 2 generates different pressure according to the position from the center O of rotation to reduce the oscillation of the floppy disk near the magnetic head.

摘要： PURPOSE:To make it possible to use both faces of a floppy disc by providing a stabilizing plate for each of both recording faces of the floppy disc and providing switching means which can shift the floppy disc so that the floppy disc is foated above the surface of one stabilizing plate and is rotated and providing a magnetic head which can write and read information onto and from the floppy disc. CONSTITUTION:When a floppy disc 2 starts rotating by a spindle 1, and the disc 2 is attracted to one of stabilizing plates 3 and 4 in accordance with rotation conditions, but the disc 2 is attracted to the stabilizing plate 4 initially. If the disc 2 should be shifted to the stabilizing plate 3, switching pins 8 and 7 are taken out and in; and when the disc 2 is floated above the stabilizing plate 3 and is rotated, data is written onto or read from the disc 2 by a magnetic head 5. If the right recording face should be accessed after accessing the left recording face, pins 7 and 8 are taken out and in to shift the disc 2 to the stabilizing plate 4 by the pin 7, and data is written or read by a magnetic head 6.
