PROBLEM TO BE SOLVED: To prevent suspensions or arms of a HSA from being deformed by heat generation of a write driver circuit while shortening a wiring length between each of read amplifier circuits and the write driver circuits and heads. SOLUTION: This disk device is constructed such that a read amplifier IC including a read amplifier circuit is mounted on the suspension 28 of each HSA 20 of an actuator 13, and a write driver IC 18 including the write driver circuit is mounted on the tip part of the main FPC 17 of which the tip part is fixed on a bearing assembly body 22. A control IC 152 including a control circuit for controlling the read amplifier in each read amplifier IC 36 and the write diver circuit in each write driver IC 18 or the like are mounted on a board main body 150 forming a fixing part of the main FPC 17. The control IC 152 is connected with each read amplifier IC 13 and write driver IC 18 via the main FPC 17.
