摘要： Because of its composition that is liable to be crystallized and therefore has a low strength, a conventional sealing glass for magnetic head has a problem in that in a manufacturing process for manufacturing a magnetic head having a narrow track width and a short gap length corresponding to the high-density recording in recent years with high accuracy, cracks are liable to be developed in a sealing glass portion by an impact caused in cutting and grinding a head chip. By using glass having a composition of 13 to 17 wt % SiO2, 5 to 6.8 wt % B2O3, 70 to 77 wt % PbO, 0.1 to 5 wt % of at least one of Al2O3 and ZnO, and 0.1 to 3 wt % of at least one of Na2O and K2O as a front sealing glass and using glass having a composition of 3 to 9 wt % SiO2, 11 to 17 wt % B2O3, 66 to 77 wt % PbO, and 3 to 15 wt % of at least one of Al2O3 and ZnO as a back sealing glass, a high-performance magnetic head having a high strength can be provided in high yields.
摘要翻译：由于其组成易于结晶并因此具有低强度，所以传统的磁头密封玻璃的问题在于，在制造具有窄轨道宽度和短间隙长度的磁头的制造过程中近年来高精度的高密度记录，由于在芯片的切割和研磨中产生的冲击，密封玻璃部分容易产生裂纹。通过使用组成为13〜17重量％SiO 2，5〜6.8重量％B 2 O 3，70〜77重量％PbO，0.1〜5重量％的Al 2 O 3和ZnO中的至少一种，和0.1〜3重量％作为前密封玻璃的Na 2 O和K 2 O中的至少一种，使用组成为3〜9重量％SiO 2，11〜17重量％B 2 O 3，66〜77重量％PbO和3〜15重量％ Al 2 O 3和ZnO作为后密封玻璃，可以高产率提供高强度的高性能磁头。
