Abstract

PURPOSE:To narrow lamination intervals of magnetic disks and to raise the mounting density of a device by using on attaching hole of a core slider supporting base as a tapped hole and using the other as a through hole to reduce the thickness of an actuator arm. CONSTITUTION:A through hole 3a and a tapped hole 3b are formed in a base 3 provided on the base end side of a beam material 2 and face the tapped hole 3b and the through hole 3a of another base 3 with an actuator arm 4 between them, and these bases can be attached to the arm 4 with one attaching screw 5. Consequently, threading of the arm 4 is unncessary, and the thickness of the arm is reduced to narrow lamination intervals of magnetic disks 6. The base 3 has the through hole 3a and the tapped hole 3b and is used as parts common to upper and lower sliders.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a support structure for a core slider for holding a magnetic head that writes and reads data, and particularly relates to a support structure for supporting a core slider for holding a magnetic head that writes and reads data, and in particular, it relates to a support structure for supporting a core slider for holding a magnetic head for writing and reading data, and in particular, it relates to a support structure for supporting a core slider for holding a magnetic head that writes and reads data. This relates to what is attached to the actuator arm.

[Prior Art] A conventional support structure for a core slider for holding a magnetic head is described in Japanese Patent Publication No. 58-22827. The support structure of this core slider for holding a magnetic head will be explained with reference to FIGS. 5 and 6.

In each figure, 1 is a core slider that holds the magnetic head 1a, 2 is a beam material, 3 is a base, and 4 is an actuator arm. The beam material 2 is made of an elastic plate material, and presses the core slider 1 attached to its tip side against the magnetic disk 6 with a constant force. Further, a base 3 provided at the other end of the beam material 2 is made of a rigid plate material, and is attached to the actuator arm 4 by a mounting screw 5.
Fixed. In magnetic disk drives, the bases 3 are often mounted on both the front and back sides of the actuator arm 4, and the two upper and lower bases 3 are provided through the through holes 3 of the bases 3.
It is fixed by upper and lower mounting screws 5a and 5b screwed into the screw hole 4b of the actuator arm 4 through the screw hole 4b of the actuator arm 4.

As a result, two core sliders 1.1 are mounted with - actuator arms 4.

Next, the operation will be explained. The core slider 1 is connected to a magnetic disk 6 which is opposed by a beam material 2, that is, the upper core slider 1 is connected to the upper magnetic disk 6a, and the lower core slider 1 is connected to the upper magnetic disk 6a.
is pressed against the lower magnetic disk 6b, and is moved to an arbitrary position on the magnetic disk 6 by an actuator arm drive mechanism (not shown) to read and write signals.

[Problems to be Solved by the Invention] Since the support structure of the conventional core slider for holding a magnetic head is configured as described above, the actuator arm 4
The mounting screws 5 need to be screwed in from above and below, making it impossible to reduce the spacing between the stacked magnetic disks, which creates a limit to the spacing between the stacked magnetic disks when trying to increase the mounting density of the magnetic disks. There were problems such as the

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a support structure for a magnetic head holding core slider that can increase the packaging density of the device.

[Means for Solving the Problems] A support structure for a magnetic head holding core slider according to the present invention includes two magnetic head holding core sliders each located on opposing surfaces of two magnetic disks. The proximal end of these beam materials is attached to the base, and then attached to both sides of the actuator arm.A screw hole is provided on one base side, and the corresponding A through hole corresponding to a screw hole is provided.

[Function] The support structure of the core slider for holding a magnetic head in the present invention is such that a screw hole provided on one base side is connected to a through hole provided in the other base and the actuator arm so as to correspond to the screw hole. Install the screws to integrate both bases into the actuator arm.

[Embodiment] A support structure for a core slider for holding a magnetic head, which is an embodiment of the present invention, will be described below with reference to FIGS. 1 to 3. Components that are the same as those in FIGS. 5 and 6 are designated by the same reference numerals, and the description thereof will be omitted.

In each figure, a base 3 provided on the proximal end side of the beam material 2 is formed with a through hole 3a and a screw hole 3b, respectively, and the through hole 3a and screw hole 3b are formed on the opposite side of the actuator arm 4. It is provided so as to face the screw hole 3b and through hole 3a of another base 3 to be attached to. Further, the actuator arm 4 has one through hole 4a formed therein. The base 3 is attached to both sides of the actuator arm 4, as shown in FIGS. It is screwed into the screw hole 3b of one base 3 through the through hole 4a.

Further, the lower mounting screw 5b is also screwed into the actuator arm 4 from below.

In the above configuration, since the actuator arm 4 does not need to be thick enough to screw the upper and lower mounting screws 5,
The actuator arm 4 can be made thinner, and the stacking interval of the magnetic disks 6 can be narrowed. Further, since the base 3 is formed with a through hole 3a and a screw hole 3a, it can be used for the upper core slider 1 and the lower core slider 1, and the base 3 can be made into a common component.

In this embodiment, the through hole 3a and the screw hole 3b are formed in the base 3, but as shown in FIG.
A through hole 3a is formed in one base 3 attached to both sides of the actuator arm 4, and a screw hole 3b is formed in the other base 3, so that the mounting screw 5 can be screwed from either the top or bottom of the actuator arm 4. You may also do so.

[Effects of the Invention] As described above, according to the present invention, the support structure of the core slider for holding a magnetic head is provided with a screw hole on one base side and a through hole corresponding to the screw hole on the other base and the actuator arm. Since a hole is provided and a screw is screwed into the screw hole through the through hole to integrate both bases into the actuator arm, the actuator arm can be made thinner and the spacing between the stacked magnetic disks can be narrowed. , the packaging density of devices can be increased.
