Abstract :
A flexible disk of continuous ferrite thin film has been prepared. Ferrite thin film media have been formed on flexible polyimide substrates through direct radio frequency (RF) sputtering deposition of Co, Cu doped Fe3O4films. The D-6dB density for the ferrite thin film, 18 K-FRPI, which is significantly higher than the 7 K-FRPI value for conventional media, was obtained with a 1.0 μm gap length ferrite head.
