Abstract

PURPOSE:To shorten the processing time of information recording and information reading by arranging plural magnetic heads on both sides of a magnetic disk and interlocking plural magnetic heads so as to movably arrange them. CONSTITUTION:The magnetic disk is inserted into a space between a lower supporting part 14 and an upper supporting part 15 in the direction of an arrow 22, and it is rotated in the direction of an arrow 13. Next, a stepping motor 1 is driven in such a way that a lower outer peripheral side magnetic head 9, a lower inner peripheral side magnetic head 10, and an upper outer peripheral side magnetic head 21 and an upper inner peripheral side magnetic head 20 are collectively shifted in the direction of an arrow 8 for a prescribed amount. The heads 9, 10, 20 and 21 are arranged in such a way that they share magnetic recording of information for the magnetic disk and the magnetic reading of information from the magnetic disk. Thus, plural pieces of information can simultaneously and magnetically be recorded or read in the magnetic heads of a same number, and the processing time of information recording or information reading can considerably be shortened.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a magnetic disk storage device as an information storage means for electronic computers and the like, and in particular to magnetic recording of information on a magnetic disk as an information storage medium and a magnetic disk. The present invention relates to the configuration of a magnetic head section for magnetically reading information from a computer.

(Prior Art) Conventionally, the number of magnetic heads in this type of magnetic disk storage device is one for each side of the magnetic disk, which is the information storage medium handled by this device, One magnetic head facing each side of the disk reciprocated over the entire storage range in the radial direction of the disk.

(Problems to be Solved by the Invention) The magnetic head of the conventional magnetic disk storage device described above is
This device handles one piece on each side of the magnetic disk, so when reading information magnetically recorded on the magnetic disk or magnetically recording information on the magnetic disk, only one piece is needed. Since the information is handled in chronological order by one magnetic head, there is a drawback that the processing time for reading or recording the information is large.

(Means for Solving the Problems) The magnetic disk storage device of the present invention has a plurality of magnetic heads disposed on each side of a magnetic disk handled by the device, and these plurality of magnetic heads are disposed in series. has been done.

(Example) Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a perspective view of one embodiment of the present invention. A step motor 1 moves a magnetic head section through a rack 3 by means of a pinion gear 2 attached to an output shaft of the motor.
It has the function of moving in the direction of. The guide rods 6 have a total of four guide rods, each having one end (on the inner circumferential side of the disk) attached to the support portion 5.
The other end (disk inner peripheral side) is fixed to the lower support part 14 or the upper support part 15. A lower outer magnetic head 9 corresponding to the outer circumferential side of the lower surface of a magnetic disk (not shown) and a lower outer circumferential magnetic head 10 corresponding to the inner circumferential side of the lower surface of the disk are respectively fixed at predetermined positions on the lower slide 7, and It has a structure that allows it to move in the direction of arrow 8 along two parallel guide rods 6. Upper outer circumferential side magnetic head 21 corresponding to the outer circumferential side of the upper surface of the disk
Further, the upper inner circumferential side magnetic heads 20 corresponding to the inner circumferential side of the upper surface of the disk are fixed at predetermined positions of the clamps 190, respectively. The clamp 19 is attached to the upper slide 16 via a rotational fulcrum of the upper slide 16 so that it can swing as shown by an arrow 17 about the upper slide 16. The upper slide 16 moves along the upper two parallel guide rods 6 in the direction of arrow 8, that is, in the disk radial direction.

The magnetic disk holding disk 18 is attached to the clamp 19 so as to be rotatable relative to the clamp 19, and the rotating shaft 18a is tilted to a stopping position in the direction of the arrow 17 so that the clamp 19 can clamp the magnetic disk. In this case, it coincides with the axis of the motor 1 located at the center of the magnetic disk and the spindle 12 attached to the output shaft of the motor 11. Lower slide 7 and upper slide 16
The racks 3 and 3 have a structure in which they are fixed to each other.

Now, insert the magnetic disk into the space between the lower support part 14 and the upper support part 15 in the direction of arrow 22, tilt the clamp 19 in the direction of arrow 17, and use the magnetic disk holding disc 18 and spindle 12 to hold the magnetic disk. Sandwich. Next, the magnetic disk is rotated in the direction of arrow 13 by driving the motor 11.

Next, on both sides of the magnetic disk, a lower outer magnetic head 9, a lower inner magnetic head 10, and an upper outer magnetic head are used for magnetically recording information on the magnetic disk or magnetically reading information from the magnetic disk. The step motor 1 is driven to move the side magnetic head 21 and the upper inner circumference side magnetic head 20 collectively by a required amount in the direction of arrow 8, which is the radial direction of the magnetic disk.

Each of the above-mentioned magnetic heads runs on the circumference from the outermost periphery to the innermost periphery of the magnetic surfaces on both sides of the magnetic disk, with one magnetic head on the lower outer periphery and one on the upper outer periphery. The magnetic head 21 and the lower inner magnetic head 10 and the upper inner magnetic head 20 respectively share the circumference from the magnetic head 21 to the innermost circumference to magnetically record information on the magnetic disk. The disk is arranged to magnetically read information from the disk.

(Effects of the Invention) As explained above, the magnetic disk storage device of the present invention has the following features:
Each side of the magnetic disk handled by this device has a plurality of magnetic heads, and these plurality of magnetic heads are connected, thereby allowing information to be magnetically recorded on the magnetic disk or recorded on the magnetic disk. When reading information, multiple pieces of information can be handled simultaneously with the same number of magnetic heads, which has the effect of significantly shortening the processing time for recording or reading information.
