对数字磁记录系统的数据恢复能力和性能所进行的理论研究,在很大程度上集中在磁头和记录介质的磁学方面,而对这种系统的电路方面则很少有文献介绍。多年来,向高记录密度方向的发展是通过改变各种系统的尺寸予以实现。高分辨率磁头信号确保了最佳的数据恢复能力。Karlquist、Hoagland 和许多其他作者已经深入地研究了记录和读出过程,进而设计了具有高数据密度的装置。最新的高密度 Theoretical studies of the data recovery capabilities and performance of digital magnetic recording systems are largely focused on the magnetics of heads and recording media with little literature on the circuitry of such systems. Over the years, the development towards high recording densities has been achieved by changing the size of various systems. High-resolution head signals ensure optimal data recovery. Karlquist, Hoagland and many others have studied the recording and reading processes in depth and have devised devices with high data densities. The latest high density
