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. According to the first and second embodiments, the space at which the head IC, the servo IC and the peripheral circuits are disposed integratedly can be secured at the connection portion of the flexible circuit board with the carriage. Therefore, the noise at the time of read/write by the heads can be reduced and a transfer rate can be improved while heat radiation by the components can be taken into consideration.
