document: Estimation of thermal coefficients of magneto-optical media Previously we described a method for estimating the thermal conductivity of magneto-optic recording media . The method relies on identifying the laser power that brings the maximum temperature of the TbFeCo layer to as high as the Curie temperature . We extensively use a similar method to estimate the heat capacity of a dielectric layer , a TbFeCo layer , and an aluminum alloy layer of magneto-optic recording media . Measurements are conducted on static disks with a beam of light focused on a TbFeCo layer . The method has the advantage of thermal diffusion depending on a multilayer structure and irradiation time
