一、磁记录的主要过程和方式磁记录是以硬磁材料(记录介质)受外磁场磁化、去掉磁场后仍能长期保持其剩余磁化强度的基本性质为基础的。磁记录包括三个主要过程:(1)消磁;(2)记录;(3)读出。根据磁记录介质的剩磁方向和介质平面的几何关系,可将磁记录方式划分为三大类(见图1):(1)纵向磁记录——剩磁方向与介质运动方向平行,并与介质的平面平行;(2)
First, the main process of magnetic recording and methods Magnetic recording is hard magnetic material (recording medium) by the external magnetic field magnetization, remove the magnetic field can still maintain its basic properties of the residual magnetization long-term basis. Magnetic recording includes three main processes: (1) degaussing; (2) recording; (3) reading out. According to the remanence direction of the magnetic recording medium and the geometric relationship of the medium plane, the magnetic recording modes can be divided into three categories (see Figure 1): (1) Longitudinal magnetic recording - the direction of remanence is parallel to the direction of the medium movement and Medium plane parallel; (2)
