省略する。(2) Background of the technology The arm for a magnetic head has the configuration shown in the schematic cross-sectional view of FIG. Reference numeral 4 indicates a magnetic disk, and as can be understood from the figure, the arm body 1 is disposed between each of a plurality of magnetic disks 4 mounted on the spindle 25. Further, the arm main body 1 is fixed to the side surface of the carriage indicated by reference numeral 26.

In other words, since the IC chip etc. are mounted on the arm body 1, there are problems in that it is not possible to miniaturize the arm body, magnetically shield the circuit on the arm, reduce noise, and eliminate lead wires. The fact that the magnetic disk drive is not miniaturized hinders the miniaturization of magnetic disk drives because it is placed between magnetic disks (2).

。The inventor of the present application made the arm body ceramic, provided an IC inside the arm to replace the conventional circuit, and integrated the arm body and IC to shield the magnetic head (3) and the storage medium from the magnetism. We considered reducing noise, eliminating lead wires, and making the arm body more compact.Furthermore, we considered making the arm body lightweight while increasing its rigidity, and increasing the resonant frequency of the mechanical system.

Wiring and connection are made to the external land 24 provided on the carriage 22. In this embodiment, since the FPC 20 shown in FIG. 3 is omitted, there is an effect that there is no resistance during arm movement. Furthermore, it is also effective in reducing the number of parts of the arm body and simplifying the arm body.

。(7) Effects of the Invention As explained in detail above, according to the present invention, (5) By making the arm body ceramic, it is possible to integrate the arm body and the circuit by installing an IC inside the arm body. As a result, the space occupied by the parts conventionally mounted on the arm can be completely saved, making the arm body smaller, magnetic shielding in the circuit, reducing noise, and eliminating lead wires in the arm body. The arm body is made of ceramic and can be constructed to be lightweight despite its high rigidity, which has the effect of increasing the resonance frequency. The miniaturization and simplification of the arm body has the effect of reducing the number of steps required to assemble the device and facilitating maintenance, which greatly contributes to improved productivity.
