The read/write characteristics of electroless-plated perpendicular magnetic recording media for flexible disks were studied using commercial VHS and 8-mm VTR ring heads. Excellent results were shown for a medium composed of Co-Ni-Re-P plated on a nonmagnetic electroless-plated Ni-P layer. A Ni-P underlayer of only 500 A greatly improved the read/write characteristics of the disk. Reproduced signals over 300 kFRPI were observed for a system using a VHS head, and D50 = 134 kFRPI was obtained using an 8-mm head.
