Abstract

In this paper, a thermally assisted magnetic recording (TAMR) head gimbal assembly (HGA) with an optical fiber and prism is proposed. The stiffness of a TAMR HGA is increased by an optical fiber and prism. Therefore, in this paper, operating shock analysis of a TAMR HGA considering the thermal effects during writing to record the data is numerically performed. Flying height (FH) analysis considering the thermal deformation by laser source also is investigated. As a result, judging from shock point of view, the shock characteristic of a TAMR HGA is better than that of conventional HGA. However, when considering the thermal effects during writing to record the data, the risk of contact for a TAMR HGA between media and slider is larger than that of conventional HGA. Hence, to solve these problems of a TAMR HGA, we should consider selection for material of media and TAMR slider, and design for head parts of TAMR slider.
