Abstract

PURPOSE:To reduce the crosstalk noise produced in a magnetic recording period by branching one end of an arm in order to increase the space between a servo head and a data head. CONSTITUTION:One end of an arm 4 is branched, and the rear edge part of a spring 2 is calked to each branch. A data head 1a is fixed to the tip of the spring 2 of one side, and a servo head 1b is fixed to the tip of the spring 2 of the other side. Thus it is possible to reduce the effect of the crosstalk noises produced in a magnetic recording mode of the head 1a to the head 1b.

に近接する方向移動した位置で動作する。A conventional magnetic head mechanism of this type is shown in FIGS. 1 and 2. In FIGS. 1 and 2, (1) is a head group. The head group (1) is composed of a data head (1a) and a servo head (1b). Reference numeral 2 denotes a spring that functions to fly the data head (1a) and the servo head (1b) over the surfaces of a plurality of magnetic disks (not shown) with a floating force suitable for magnetic recording and reproduction. (3) It is a caulking part. (4) is the head group (
This is an arm for supporting 1). Spring (2)
The head group (1) is supported by the arm (4) by fixing the rear end thereof to the arm (4) with a caulking portion (3). A plurality of magnetic disks (not shown) are arranged at regular intervals, and the magnetic head mechanism shown in FIG. 1 is located between the magnetic disks (not shown). Since the spacing between magnetic disks (not shown) is generally about 7.5 m,
The data head (1a) and the servo head (1b) operate at positions where they are moved in a direction closer to each other.

) is the arm. One end of the arm (4) is branched, and the rear end of the spring (2) is fixed to each branched portion by caulking. (3) is the caulking part. A data head (1a) that performs magnetic recording and reproduction is fixed to the tip of one spring (2), and a servo head (1b) that reproduces magnetically recorded servo information is fixed to the tip of the other spring (2). Thus, the spatial length between the data head (1a) and the servo head (1b) is expanded.
