Magnetic recording medium

摘要

Provided is a magnetic recording medium suited to magnetic recording and reproduction systems employing linear methods and incorporating magnetoresistive reproduction heads. The magnetic recording medium comprising a magnetic layer for servo signal recording, a nonmagnetic layer, and a magnetic layer for information recording in this order on a nonmagnetic support, wherein said magnetic layer for information recording exhibits a coercivity of at least 7.96 kA/m (100 Oe) higher than a coercivity of said magnetic layer for servo signal recording and an interface roughness at the interface of said magnetic layer for servo signal recording and said nonmagnetic layer ranges from 7 to 12 nm.
