MAGNETIC RECORDING MEDIUM, METHOD FOR MANUFACTURING RECORDING MEDIUM AND MAGNETIC RECORDING APPARATUS |
摘要 |
A magnetic recording layer is formed on an under-layer comprising a Cu crystalline grain layer and a deposited nitrogen atom layer on the Cu crystalline grain layer surface. Then the magnetic recording layer comprising very small average grain diameter and sharp grain diameter distribution is obtained. The magnetic recording medium comprising the magnetic recording layer shows excellent signal to noise ratio at high density recording.
