からの引出線を。Generally, in a recording device that records on a magnetic disk-shaped magnetic recording medium, the magnetic head that reads, writes, and erases information from the magnetic recording medium is elastically supported by a thin leaf spring called a gimbal, and the magnetic head is This enables the head to follow the undulations of the magnetic recording medium, thereby ensuring stable recording and reproduction at all times.
In a conventional magnetic head support device, the read/write coil and erase coil constituting the magnetic head are connected to the outside by 1. For example, as disclosed in Japanese Patent Publication No. 56-6058, signals from the coils are connected using copper wires. 9, for example, as disclosed in Japanese Patent Publication No. 57-4009, a lead wire from a coil.

装置を提供することにある。This flexible printed cable has a structure that draws out signals from a flexible printed cable that is either directly attached to the magnetic head or fixed to the gimbal movable part near the magnetic head. A thin conductor such as copper foil is wired on a synthetic resin film by means such as etching. When the above-described lead-out method is used, the rigidity of the metal lead-out wire or flexible printed cable impairs the mobility of the magnetic head, making it difficult to obtain a stable head touch against undulations of the medium. In addition, depending on the molding state of the metal lead wire or flexible printed cable during assembly and adjustment, the magnetic head may initially be caused to undergo unnecessary displacement, making stable recording and reproduction of the medium impossible. Purpose] An object of the present invention is to provide a magnetic head support device having a leader wire attachment structure that does not adversely affect the posture or tracking characteristics of the magnetic head.

。A feature of the present invention is that the lead wire from the magnetic head is wired integrally with the gimbal. This structure of the leader line does not adversely affect the attitude and tracking performance of the magnetic head, so that recording and reproduction can always be performed stably.

It is a two-degree-of-freedom gimbal that allows rotation around two orthogonal in-plane axes having a diameter of 2b. This gimbal 2 is often made of a spring material such as stainless steel or beryllium copper.
High strength polymeric materials such as polyimide can also be used. The gimbal pattern of the gimbal 2 is formed by etching or punching. magnetic herad 1
Leader wires 8 for read/write coil 1a and erase coil 1b.

る。This conductor layer is formed into the shape of a leader line 7.8 by means such as photoetching. Furthermore, if a non-conducting polymeric material is used as the base material of the gimbal 2, the above-mentioned insulating layer can be omitted, and a conductive layer such as copper foil is provided directly on the gimbal 2. By integrally forming the drawers m8 and 9 on the gimbal 2 in the shape of a lead wire 8°9 by photo-etching or other means, the posture and movement of the magnetic helad 1 up to the drawer terminal 10 can be improved. It would also be possible to draw the leader line 8.9 without affecting the . For wiring from the extraction terminal 10 to the control board, a flexible printed cable 4 may be used, but even if metal wires such as ordinary stranded wires with high rigidity are used, the posture and movement of the magnetic head may be affected. Therefore, there is no need to use a flexible printed cable 4 that takes flexibility into consideration. In this case, the omission of the flexible print cable 4 improves ease of assembly. By omitting the flexible printed cable, no external force is applied to the gimbal 2, which stabilizes the posture of the magnetic head and improves performance.
