Abstract :
A new technique for producing high impact resistance plastic hard disks is introduced. Plasma-based ion-implantation (PBII) using hi-polar high-voltage pulses is applied to the plastic substrate, then magnetic and hard-coat layers are fabricated on the substrate. The PBII-treated plastic hard disk had a critical acceleration value of 230 G from an impact test, while an aluminum hard disk had a value of less than 90 G
