Abstract

The embodiment provides a disk device capable of adjusting the temperature of a flexible printed circuit board at the time of connecting terminals. A disk device according to one embodiment includes arecording medium, a magnetic head, a wiring member, and a flexible printed circuit board. The magnetic head is configured to read / write information from / to the recording medium. The wiring member includes a plurality of first terminals, and a plurality of first wires that electrically connect the magnetic head to the first terminals. The flexible printed circuit board includes a surface, a plurality of second terminals located on the surface to be connected to the first terminals by means of a conductive adhesive, and a ground plane spaced apart from the second terminals in a direction alongthe surface.

Description

[0001] Associate application [0002] This application enjoys the priority of the basic application based on Japanese Patent Application No. 2019-170065 (filing date: September 19, 2019). This application incorporates the entire content of the basic application by referring to this basic application. technical field [0003] Embodiments of the present invention relate to disk devices. Background technique [0004] A disk device such as a hard disk drive (HDD) has a magnetic disk and a magnetic head for reading and writing information to the magnetic disk. For example, a flexible part, a flexible printed circuit board (FPC), electrically connects a control device controlling the HDD and a magnetic head. The terminals of the flexible member and the terminals of the FPC are connected to each other by, for example, solder. However, the quality of the disk device may change due to the temperature of the solder and the vicinity of the solder when the terminals are connected wit...
