ABSTRACT:
A magnetic recording device includes a magnetic disk for storing information, a magnetic head for writing and reading information relative to the magnetic disk, a device for rotating the magnetic disk relative to the magnetic head in such a manner that speed of said magnetic disk relative to the magnetic head is 6 to 40 m/s at an innermost track of the magnetic disk, and a device for applying a load to the magnetic head so that a gap between the magnetic disk and the magnetic head disposed in opposed relation to the magnetic disk can be kept to not more than 0.1 .mu.m.
