Effects of temperature on flying height of TMR recording head in hard disk drive during writing and reading operations

摘要

Currently, the requirement of hard disk drive for storing data is increasing. At the same time, the quality of hard disk drive is also important to prevent damages of data. The flying height of recording head affects on the recording performance. In this paper, an experimental method is used to characterize the effects of temperature on flying height with TMR recording head during writing and reading operations. The results show that the temperature affects on the flying height of recording head during writing and reading operation that can cause data errors.
