MAGNETIC RECORDING MEDIUM

摘要

PURPOSE:To moderate the hardness and flexibility of the magnetic layer of the titled medium by incorporating two kinds of polyesters each having a specified glass transition temp. into the magnetic layer. CONSTITUTION:A polyester having >=50 deg.C glass transition temp. and a polyester having <=10 deg.C glass transition temp. are jointly used in the magnetic layer as the binder. A magnetic layer having a moderate hardness and flexibility can be obtained by this constitution, and a magnetic recording medium having excellent electromagnetic transducing characteristic and durability can be obtained.
