Abstract

The present invention relates to a main printed board for hard disc driver and a hard disc driver thereof. In the main printed board for hard disc driver and the hard disc driver thereof, a connection part of a suspension printed board can be provided with an accurate interconnection which is formed with high density, and furthermore the bending resistance and durability in the part to be bended repeatedly can be ensured. The main printed board (15) used for the hard disc driver is fixed to the side part of a carriage (7) of an access arm that is supported in a swinging mode. The main printedboard is provided with a top side connected with the suspension printed board (11) and is provided with a base side which extends flexibly. The main printed board comprises a fixed part (15a) which is connected with the side part of the carriage and is furthermore connected with the suspension printed board, and an extending part (15b) which extends from the base side of the fixed part. The fixedpart and the extending part are formed respectively through different manufacturing methods. Furthermore the main printed board comprises a connection part (41) for connecting the fixed part and the extending part.

Description

technical field [0001] The invention relates to a main printed board for a hard disk drive. More particularly, the present invention relates to a main printed board for a hard disk drive as described below, which allows precise formation of connection interconnections at high density and can secure conventional flexibility, and also relates to the hard disk drive. Background technique [0002] A hard disk drive, which is generally used as a storage device for a computer, includes a magnetic disk that carries information and is supported by a motor for rotation, and also includes a magnetic head core for writing / reading information on / from the magnetic disk. The head core is held by a head arm assembly for swinging along the surface of the magnetic disk (for example, see Japanese Patent Laid-Open No. 2008-59663). [0003] The head arm assembly includes a carriage supported by a voice coil motor (VCM) so as to swing about its axis, and a suspension disposed at an arm of the c...
