Evaluation of Head/Disk interface using TAA Signal

TAA신호를 이용한 하드디스크의 헤드/디스크 인터페이스 분석

  • Published : 2001.03.01


The durability of head/disk interface is an important issue for hard disk drives. Currently, there are several means of assessing the performance and integrity of the head/disk interface. In this work Track Average Amplitude(TAA) signal was used to analyzed the head/disk interface with respect to variations in disk velocity, slider pre-load and preformed scratch on the disk. Particularly, TAA variation due to disk defect in the form of a scratch was investigated.
