Abstract
In a disk device including, on a base, at least one recording disk rotated by a spindle motor, a carriage equipped with heads for executing read/write operations with the recording disk and a voice coil motor for driving the carriage, whereby the carriage includes an arm portion for mounting the heads at a distal end thereof, a main body equipped with a rotary shaft and a rotor portion serving as a rotor of the voice coil motor, the present invention provides a carriage structure capable of reducing noise and accomplishing a high transfer rate. According to the first embodiment, an anchor member comprising a flat sheet portion and an extension portion and made of a sheet metal is disposed on the flat surface portion of the side surface of the carriage main body, and a flexible circuit board is wound on the anchor member and is, in this state, connected to the carriage. Therefore, a package area on the carriage side can be increased. According to the second embodiment, a control IC of a bare chip is packaged to a connection portion of the flexible circuit board and the carriage by a flip packaging method, and other chip components are packaged by a surface packaging technology.
