Discrete Tracks for Saturation Magnetic Recording

Abstract
Discrete-track recording is a magnetic-recording method which employs a single-gap head and a discrete-track medium to increase the head-repositioning tolerance in saturation digital recording. A head with a conventional ring structure may be used. The recording medium consists of discrete magnetic tracks separated by nonmagnetic lands. Width of the magnetic tracks depends largely on the desired track density and maximum tolerable head-repositioning error. Test results indicate excellent track performance; consequently, satisfactory and reliable operation can be expected under actual machine conditions. Major advantages of discrete-track recording are economy, reliability, and increased head-repositioning tolerances.
