Title: Low noise flexible printed circuit cable for a disk drive carriage unit

Abstract: An FPC cable which is excellent in noise resisting property, manufacturing cost, mounting operability to a carriage, and maintenance. The FPC cable includes a spacer and a reinforcing plate. In the patterned surface of the FPC, a head pad to which a head wire is bonded is formed on a pad forming portion and a preamplifier chip is mounted on a device mounting portion. Wiring patterns are linearly connected between the head pad and the preamplifier chip and between the preamplifier chip and an I/O-side end portion, respectively. In the spacer, a cavity is formed for storing the preamplifier chip. The reinforcing plate is inserted into the space formed by folding back the pad forming portion, and the spacer is engaged with the device mounting device, thereby constituting a magnetic-head-side end portion.
