Abstract
A simple thin film head called the Mellisuga head has been developed. The head has an extremely low flying height (0.03 mu m-0.07 mu m). The reliability in the contact start stop (CSS) process and the soft dynamic load/unload (SDL) process of the head on two types of thin film disk was investigated. In the Mellisuga head, operation in a gamma -Fe/sub 2/O/sub 3/ disk with a glass substrate, at 50000 CSS and 100000 SDL cycles, was completed successfully. This confirms that the gamma -Fe/sub 2/O/sub 3/ disk has an advantage for Mellisuga head operation. It is shown that the head could be operated on a metal disk with a glass substrate during the SDL process. >
