磁头的制造方法以及用于该制造方法的加工夹具
摘要：
本发明的目的在于提供一种经过简单并迅速的处理就能够高精度地形成MR高度和颈高度的磁头制造方法，并提供一种用于该制造方法的加工夹具。其中，所述磁头制造方法包括以下步骤：将长形条安装在具有若干夹具光学标记的加工夹具上，该长形条上形成了若干具有读取元件和写入元件的磁头。检测安装了长形条的加工夹具上的若干夹具光学标记的位置，并且检测长形条上设置的若干长形条光学标记的位置。根据检测出的若干夹具光学标记位置和若干长形条光学标记的相对位置关系，来求算长形条的实际变形量，当长形条的实际变形在容许范围之外时，卸下长形条再重新安装，然后对安装在加工夹具上的长形条进行加工，再将其切割成单个磁头。
摘要（英）：

The invention aims to provide a method for making magnetic heads, which can form the magnetic heads with MR height and neck height precisely by simple and quick processing, and provides a processing clamp used for the making method. The method for making magnetic heads comprises the following steps of: installing a long strip on the processing clamp having a plurality of optical clamp marks, wherein a plurality of magnetic heads with read elements and write elements are formed on the long strip; detecting the positions of the optical clamp marks on the processing clamp provided with the long strip, and detecting the positions of the optical long strip marks arranged on the long strip; and calculating the actual distortion of the long strip according to the relative position relationship between the positions of the optical clamp marks and the optical long strip marks, removing and reinstalling the long strip when the actual distortion of the long strip exceeds the permissible range, then processing the long strip installed on the processing clamp, and then cutting into individual magnetic heads.
