Descriptions
The existing theories dealing with the isolated readback signal of digital magnetic recording employ internal magnetization width as a basic parameter describing a written medium. In this paper, another analysis of isolated readback process has been made by utilizing the surface flux density emerging from the surface of a recorded medium. The solution obtained not only has a simple form, but it makes easy to predict the readback properties in a practical sense.
