Magnetic recording medium

摘要

A magnetic recording medium is disclosed wherein the data tracks are formed of magnetic layers and the non-data tracks are formed of non-magnetic layers. The data tracks and non-data tracks are alternately disposed and the non-data tracks do not effect recording/reproducing/erasing of the data tracks. Another medium is disclosed wherein the magnetic and non-magnetic layers are alternately disposed in the direction of recording/reproducing and the magnetizing transition width is shortened so that the bit length may be shortened. A reproducing apparatus is also disclosed which includes a discriminator for discriminating the magnetizing direction of the magnetic layer on the data tracks on the basis of a detection signal fed from the reproducing head.
