应用磁记录理论设计了一种新型窄道宽软盘磁头，利用自制和国产加工设备，辅以进口检测设备对该磁头进行了试制，着重分析了研磨工艺品质问题以及玻璃烧结过程中裂纹的产生和预防，并通过联机测试验证设计及工艺的正确性． A new type of narrow-width floppy disk head was designed based on magnetic recording theory. The head was tested by self-made and domestic processing equipment, combined with imported testing equipment. The problems of grinding process quality and the occurrence of cracks in glass sintering process were analyzed Prevention, and through online testing to verify the correctness of the design and process.
