  • Abstract
    Contact perpendicular magnetic recording on both sides of a hard disk was attempted, using a head suspension mechanism employing a spring for vertical motion. A head-to-medium spacing of about 300Å was maintained at speeds up to 11 m/s over all tracks on the disk. The results show that the distribution of magnetic properties of the recording layers on the hard disk are directly reflected in the envelope and the recording and playback characteristics. Data was successfully recorded at 100 kFRPI and a track width of 60 ¿m.
