ABSTRACT:
A first thermal buffer layer and a second thermal buffer layer are arranged between a recording medium and an actuator structure. The heat conductivity of the first thermal buffer layer is set low and the heat conductivity of the second thermal buffer layer is set high. Most of the heat generated from a coil wiring of the actuator structure is blocked by the first thermal buffer layer, and heat leaked from the first thermal buffer layer is diffused by the second thermal buffer layer. Temperature distribution on the recording medium is made uniform, and thus, a configuration wherein the recording medium and the actuator structure are placed one over another can be provided, information reading accuracy or information recording stability can be improved and the sizes of an information storage device can be reduced.
