Abstract
A magnetic disk device includes a flexible printed circuit board having a first portion provided with read/write ICs for read/write heads and first printed patterns connected to the read/write ICs and a second portion positioned within the first portion, an end of the second portion being connected to the first portion so as to be bendably projected from the first portion, the second portion being provided with a servo IC for the servo head and second printed patterns connected to the servo IC, the flexible printed circuit board being mounted on an actuator body such that one end of the first portion lies outside the actuator and the second portion lies on the actuator body. The magnetic disk device also includes first lead wires of the read/write heads extending to the flexible printed circuit board and being connected to the first patterns, and second lead wires of the servo head extending to the flexible printed circuit board and being connected to the second printed patterns. The first lead wires and the read/write ICs are on one side of an imaginary plane while the second wires and the servo IC are on an opposite side of the imaginary plane, the imaginary plane passing through the tip end of an arm structure and a shaft of the actuator body and being parallel to the shaft.
