Abstract :
A simple thin film head called the Mellisuga head has been developed. The head has an extremely low flying height (0.03 μm-0.07 μm). 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 γ-Fe2O3 disk with a glass substrate, at 50000 CSS and 100000 SDL cycles, was completed successfully. This confirms that the γ-Fe2O3 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
