Abstract
A tape-type magnetic recording medium including a non-magnetic support member; and a magnetic layer formed on the non-magnetic support member, wherein relationship Br.delta..ltoreq.Bst/2 is satisfied when an assumption is made that the residual magnetic flux density of the tape-type magnetic recording medium is Br, the thickness of the magnetic layer is .delta., the saturated magnetic flux density of a magnetoresistance effect device for use in a shield-type magnetoresistance effect magnetic head serving as a reproducing head is Bs and the thickness of the same is t, and coercive force Hc of the tape-type magnetic recording medium satisfies Hc.gtoreq.1500 (Oe).
