Perpendicular magnetic recording using a main-pole-driven perpendicular head was tested for the first time using electroless-plated flexible disks. Soft magnetic NiFeP films, also produced by electroless plating, were used as an underlayer of a perpendicular recording medium in this test. Two types of flexible double-layer media, composed of an electroless-plated CoNiReP film with two types of NiFeP underlayers with a coercivity of 2 and S.S Oe, developed in this study, were fabricated, and their recording characteristics were measured. A higher D50 value of 75 kFRPI was obtained for the medium with the 2-Oe underlayer. The output voltage for the medium with the softer magnetic 2-Oe underlayer was about twice as high as that for the medium with the 5.5-Oe underlayer.
