SPUTTERING TARGET FOR FORMING ADHESION LAYER OF HEAT-ASSISTED MAGNETIC RECORDING MEDIUM, AND ADHESION LAYER FOR HEAT-ASSISTED MAGNETIC RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a sputtering target that can form an adhesion layer for a heat-assisted magnetic recording medium having both an amorphous structure and a high thermal conductivity, and an adhesion layer for a heat-assisted magnetic recording medium.;SOLUTION: A sputtering target for forming an adhesion layer of a heat-assisted magnetic recording medium has a compositional formula in an atomic ratio represented by Cr_100-X-YNb_XTi_Y, 5≤X≤70, 0≤Y≤50, and 35X+Y≤70, with the balance being inevitable impurities. There is also provided an adhesion layer for a heat-assisted magnetic recording medium.;SELECTED DRAWING: None;COPYRIGHT: (C)2018,JPO&INPIT
