    • Embodiments in accordance with the present invention allow control over the element height of read and write heads without damage to a lapping surface table when an air-bearing surface is lapped with a row bar or magnetic head slider tilted. According to one embodiment, when a row bar is tilted in the longitudinal direction of a slider to lap its air-bearing surface according to the positional deviations of a read element and a main magnetic pole piece, an inclination angle θc is changed stepwise in order of θc, θx and θt, with respect to a target inclination angle θt and the row bar is lapped while being swung by α in the longitudinal direction of the slider around an inclination angle at each step. A swing width a is controlled to gradually attenuate. Thus, the element heights of the magnetic pole piece and the read element can be controlled without damage to a lapping surface table.
    • 根据本发明的实施例允许控制读写头的元件高度,而在用行杆或磁头滑块倾斜的空气轴承表面被研磨时,不会磨损研磨表台。 根据一个实施例,当行杆沿着滑块的纵向方向倾斜以根据读取元件和主磁极片的位置偏差来卷绕其空气轴承表面时,倾斜角度按顺序逐步改变 在相对于目标倾斜角度的情况下,相对于目标倾斜角度,行条被翻转,同时在滑块的纵向方向上以α倾斜度围绕倾斜角在每一步摆动。 摇摆宽度a被控制以逐渐衰减。 因此,可以控制磁极片和读取元件的元件高度而不损坏研磨表面台。

    • Disclosed is a method, in which when a liquid material is applied to the application surface of an object of application by using a liquid material supply device having a syringe containing the liquid material and equipped with a needle having at its distal end an ejection hole from which the liquid material is ejected, an image of the distal end of the needle is taken laterally by a horizontal camera together with a height reference mark when an ascent/descent drive system of the liquid material supply device is set to a reference height, and the height position of the distal end of the needle is obtained from the difference between the height of the distal end of the needle and the height of the height reference mark.
    • 公开了一种方法,其中当通过使用具有含有液体材料的注射器的液体材料供应装置将液体材料施加到施加物体的施加表面上并且配备有在其远端具有喷射孔的喷射孔时, 当液体材料供给装置的上升/下降驱动系统被设定为参考高度时,液体材料被喷射的情况下,水平摄像机的横向摄像机与高度参考标记一起被拍摄针的远端的图像,以及 针的远端的高度位置是根据针的远端的高度与高度参考标记的高度之间的差来获得的。
