摘　　要：混合伺服技术最早见于IBM3310。本文全面介绍分析了它的基本原理与实现方法,从中可见这种技术的先进性,对实践具有一定的指导意义。尤其扇段伺服的设计有新颖独到之处,采用了一种“对消伺服花样”,使得比较过程在磁头本身中完成。为了有效地处理微弱信号,改进了伺服解调电路。This article introduces and analyses the principles and ways of hybrid servo technology first presented in IBM 3310.Especially in designing sector servoes, an arrangement of position reference information, known as 'Null Servo Pattern', is used. Because of comparision carried out in the head itself and improvement in servo demodulating circuitry, this arrangement is highly efficient in processing the servo signal.
