颗粒磁记录材料进展

Advances of particulate magnetic recording materials

论述了颗粒磁记录材料氧化铁、二氧化铬、钴改性的氧化铁、金属磁粉和钡铁氧体颗粒的发展和应用。近年来,国内外开发的NP氧化铁磁粉,包钴NP磁粉、金属磁粉和钡铁氧体颗粒,将在音像技术、数字磁盘等高记录密度领域中占据重要地位。

The development and applications of particulate magnetic recording materials, such as iron oxide, chromium dioxide, cobalt modified iron oxide, metallic magnetic powder and barium-iron-oxygen particles are reviewed. In recent years the newly developed at home and abroad NP iron oxide magnetic powder, cobalt-surface-modified NP particles, metallic magnetic powder and barium-iron-oxygen particles will have an important role to play in high recording density applications such as in the areas of audio-video technology and digital disks.
