【０００２】0002
例えば従来のフレキシブルディスク用の磁気ヘッド（１０）は図２および図３ に示すように磁気コア組立体（３）を備え、その両側に、チタン酸カルシウムあ るいはチタン酸バリウムあるいは非磁性フェライト材等からなる焼結体で形成さ れたスライダー（４）（４）が接合されている。 For example, a conventional magnetic head (10) for a flexible disk is shown in FIGS. 2 and 3. As shown in the figure, the magnetic core assembly (3) is provided with calcium titanate on both sides. The material is made of barium titanate or a sintered body made of non-magnetic ferrite material. The sliders (4) (4) are joined together.
【０００３】 そしてこの磁気ヘッド（１０）は図３においてスライダー（４）の下面（４ａ ）が磁気記録媒体（図示せず）との対接面となり、その反対側の上面（４ｂ）は 例えばベリリウム銅、ステンレス薄板等からなる金属弾性体の取付板であるジン バルバネ（２０）に合成樹脂あるいは接着剤等によって接合され、更にこのジン バルバネ（２０）の上に両面接着テープ、接着剤等を介在させてフレキシブルプ リント基板（１）が取付けられている。0003 This magnetic head (10) is located on the lower surface (4a) of the slider (4) in FIG. ) is the surface facing the magnetic recording medium (not shown), and the upper surface (4b) on the opposite side is the surface facing the magnetic recording medium (not shown). For example, a mounting plate for a metal elastic body made of beryllium copper, stainless steel thin plate, etc. It is bonded to the valve spring (20) with synthetic resin or adhesive, and this resin is Apply double-sided adhesive tape, adhesive, etc. to the flexible spring (20) A lint board (1) is attached.
【０００４】 そして該フレキシブルプリント基板（１）には外部との信号の授受を行うため の導電パターン（１ａ）が形成されており、該導電パターン（１ａ）の端部には 前記磁気ヘッド（１０）のコイルボビン（５）に埋設された端子（６）が接続さ れている。前記コイルボビン（５）にはコイル（７）が巻回され、該コイル（７ ）からのリード線（図示せず）が前記端子（６）に接続され、該コイルボビン（ ５）は磁気ヘッドの磁気コア（３）に装着されている。0004 The flexible printed circuit board (1) is used to send and receive signals to and from the outside. A conductive pattern (1a) is formed at the end of the conductive pattern (1a). A terminal (6) embedded in the coil bobbin (5) of the magnetic head (10) is connected. It is. A coil (7) is wound around the coil bobbin (5). ) is connected to the terminal (6), and the coil bobbin ( 5) is attached to the magnetic core (3) of the magnetic head.
【０００５】 ところで近年軽薄短小の傾向はこの種のフレキシブルディスク装置にもおよび 、該装置の薄形化、小型化を図るためには装置に使用する部品の薄形化、小形化 が要求されている。[0005] Incidentally, in recent years, the trend towards lighter, thinner, shorter and smaller devices has also spread to this type of flexible disk device. In order to make the device thinner and smaller, the parts used in the device must be made thinner and smaller. is required.
【０００６】[0006]
しかしながら図３に示すような磁気ヘッドのフレキシブルプリント基板の取付 構造では、磁気回路を構成する磁気コア、コイルを巻回したコイルボビンスライ ダー等の薄形化小形化を極限まで行っており、これ以上磁気回路を構成する部分 の薄形化、小形化をすると例えば記録再生特性の劣化をきたし使用できなくなる という問題がある。 However, when mounting a flexible printed circuit board for a magnetic head as shown in Figure 3, The structure consists of a magnetic core that makes up the magnetic circuit, and a coil bobbin sliver around which the coil is wound. We have made the parts that make up the magnetic circuit as thin and compact as possible. For example, if the device is made thinner or smaller, its recording and playback characteristics deteriorate, making it unusable. There is a problem.
【０００７】 本考案は、この様な点に鑑みなされたものでジンバルバネのフレキシブルプリ ント基板の取付部分を段差を介して他の部分よりも肉薄に形成し、この肉薄化に よって磁気ヘッド全体の薄型化を図ることを目的としている。[0007] This invention was developed in consideration of these points, and is a flexible spring for gimbal springs. The mounting part of the component board is formed thinner than other parts through a step, and this thinning is achieved by Therefore, the objective is to make the entire magnetic head thinner.
【０００８】[0008]
本考案は、磁気ヘッドのスライダーにジンバルバネを介して取付けるフレキシ ブルプリント基板の取付構造において、前記ジンバルバネのフレキシブルプリン ト基板の取付部分を他の部分に対し肉薄に形成した構成とする。 This invention is based on a flexible cable that is attached to the magnetic head slider via a gimbal spring. In the mounting structure of the flexible printed circuit board, the flexible printed circuit board of the gimbal spring The mounting part of the top board is formed thinner than other parts.
【０００９】[0009]
上記のようにジンバルバネのフレキシブルプリント基板の取付部分を段差を介 して他の部分よりも肉薄にすることにより、磁気ヘッド全体の厚さを薄くでき、 ひいてはフレキシブルディスク装置の厚さを薄くすることができる。また、ジン バルバネに形成される段差を利用してフレキシブルプリント基板の位置決めを容 易に行なうことができる。 As shown above, attach the mounting part of the gimbal spring's flexible printed circuit board through the step. By making the magnetic head thinner than other parts, the overall thickness of the magnetic head can be reduced. As a result, the thickness of the flexible disk device can be reduced. Also, Jin The positioning of flexible printed circuit boards is facilitated by using the steps formed on the bulb springs. It can be done easily.
