Abstract
A magnetic recording medium stable against heat of which high density recording can be attained is provided by employing a magnetic material such that coercive magnetic force in a recording magnetic layer increases with temperature rise. The magnetic recording medium is one in which the recording magnetic layer in which magnetic recording is carried out comprises an N-type Ferrimagnetic material, and compensation temperature of this N-type Ferrimagnetic material is made to be higher than an operating temperature range in which the magnetic recording medium is used.
