Thermally-assisted magnetic recording (TAMR) is one of the most effective ways to increase the recording density of hard disk drives. A laser diode (LD) is assumed as a heat source of TAMR, and the light delivery mechanics from an LD to a slider of a head gimbal assembly (HGA) in a hard disk drive is a key component of TAMR We designed, prototyped, and evaluated a HGA with a flexible beam that is considered to be a light path from an LD to a slider. Its evaluated results show good mechanical properties as an HGA. The stable flying height and small vibration of the assembly with a flexible beam were practically confirmed. It was concluded that the mechanics of light delivery using a flexible beam in an HGA has limited effect on the mechanical properties of an HGA.
