The aim of the MIHFAD project is to develop some of the key technologies required for the development of high-density, high-performance miniature disk-drives. Miniature magnetic heads represent one of the key components that will shape the overall properties of the final disc drive.
There is a continuing trend towards the miniaturisation of disk drives, as evidenced by the successive development of 5.25", 3.5", 2.5" and now 1.8" diameter devices. MIHFAD's target storage density of 400 Mbits per square inch is will enable the demonstration of 2.5" and 1.8" diameter drives with capacities of 320 Mbytes and 160 Mbytes respectively (two times those available in 1993).
In order to achieve such characteristics, the key technologies that need to be mastered are related to:
The work performed up to now has permitted to select a magnetic material with high saturation magnetisation and with appropriate characteristics for the application. A pico slider in the format of 35% has been designed and has proven to exhibit good flying characteristics with a suspension which has been specifically adapted. Tests experiments have been performed with prototypes of magnetic heads and have performances which are close to the final goal of the project.
The forecast coming from prospects with customers and market analysis indicate that the entry into production of pico sliders will occur during 1995. With the end of the project occurring at the mid of 1984, the consortium will be in a good position on this new technology. SILMAG intends to progressively shifts its production from the nanoslider format to the pico slider formats during the years 1995-96.
