• A new type center aperture detection (CAD) magnetically induced super-resolution (MSR) disk is described. A magneto-static type CAD disk was already reported last year, and it improves readout stability without deteriorating the readout characteristics such as readout resolution by using a gadolinium intermediate layer instead of a non-magnetic layer. Our group studied the intermediate layer further, and realized the exchange coupling type CAD disk that has high-resolution and readout stability simultaneously by using GdFeCo intermediate layer. It has large tolerance to the external magnetic field at readout. The tolerance became about three times larger than the magneto-static coupling typeCAD reported before.
