Abstract
To understand why barium ferrite (BaFe) tape exhibits low friction and small spacing loss, the magnetic spacing, transition parameter and head/tape physical spacing were investigated and compared with metal particle (MP) tape. As a result, we found that using BaFe tape can reduce both the magnetic spacing and the transition parameter while maintaining a similar friction (physical spacing) as that of MP tape. The ability to reduce these parameters is considered to be due to a particle property specific to barium ferrite. These results suggest that BaFe tape is superior to MP tape for high-density recording.
