Embodiment Construction

[0013] Please refer to Figure 1 to Figure 3 , the present invention is a new disk drive, including a disk base 10, a magnetic head assembly and a voice coil motor 60 for driving the head assembly to rotate.

[0014] A disk installation area is formed in a recess on the disk base 10, and at least one disk (not shown) is installed in the disk installation area. The magnetic head assembly is installed on one side of the disk.

[0015] The magnetic head assembly includes several suspension arms. In this embodiment, two suspension arms 31 and 32 are used. Ends of the cantilever 31 and the cantilever 32 are respectively connected to elastic carrying arms 37 and 38 . Magnetic heads 41 and 40 are suspended from the ends of the carrying arms 37 and 38 respectively. The cantilevers 31 , 32 are fixed on a bearing 34 , and the bearing 34 is supported on a rotating shaft (not shown) on the base 10 .

[0016] Please also see Figure 4 , the magnetic heads 41 and 40 at the ends of the ...

Abstract

The invention relates to a new type of magnetic head assembly, comprising a pair of cantilevers, each cantilever end is connected with an elastic carrying arm, each end of the carrying arm is suspended with a magnetic head, and the magnetic heads at the ends of the two carrying arms are used to read and write the upper and lower sides of a magnetic disk The data. The magnetic heads on the carrying arm are staggered from each other. The present invention also relates to a disk drive using the magnetic head assembly, the opposing magnetic heads are offset so that the magnetic heads will not stick to each other and cause damage when the magnetic head assembly is installed.

Description

【Technical field】 [0001] The invention relates to a disk drive, in particular to a disk drive which can facilitate the installation of a magnetic head assembly while ensuring that the magnetic head is not damaged. 【Background technique】 [0002] Existing disk drives generally include a base and a disk installed in the base. The disk surface is covered with magnetic media and is mounted on a spindle motor shaft that rotates at a constant high speed. The reading and writing of data on the magnetic disk is accomplished by the magnetic head on the magnetic head assembly driven by the voice coil motor. The magnetic head is installed at the ends of the two carrying arms of the magnetic head assembly face to face. Because the carrying arm has elasticity, when it is in a free state, two magnetic heads facing each other will stick together to cause damage to the magnetic head. [0003] In the assembly of the traditional magnetic head assembly, tools such as comb teeth are needed t...
