Abstract
A magnetic storage medium includes a magnetic storage medium that exhibits a magnetic compensation temperature specified higher than room temperature to minimize effects of heat generated by a head using magneto-resistance effect. In a heat assisted recording and reproduction method using such a magnetic storage medium, during reproduction, the S/N ratio in a reproduction signal is enhanced by optimizing the bias current applied to the head using magneto-resistance effect. A magnetic storage medium and a heat assisted recording and reproduction method using such a magnetic storage medium whereby information is magnetically recorded and reproduced by heating a read-out domain are offered that enables signal reproduction with a good S/N ratio despite possible use of a head exhibiting magneto-resistance effect.
