Thermal stability of TM-rich Tb_x(Fe_<90>Co_<10>)_<100-x>(x=13.5,17.2) disks (K_uV/k_BT) is estimated by a reverse DC-erase noise method and the Sharrock's equation. The method involves a spinstand for hard disks, and hard disk glass substrates with TbFeCo deposited as a magnetic layer of perpendicular anisotropy were used. As the result, the high stability was shown for a high coercivity disk. This indicates that the pinning effect, which is related to coercivity, is one of the important factors for thermal stability.
