To serve the needs of high linear bit density recording and high data transfer rate, a new perpendicular recording hard disk media constitution is proposed. In the new hard disk media, a Co-Cr layer is directly deposited on a soft-magnetic Mn-Zn single-crystal ferrite substrate. The ferrite substrate hard disk showed superior high-frequency response to a conventional Co-Cr/Fe-Ni-Nb double-layered hard disk with glass substrate. This improvement in high frequencies is brought about by suppressing the eddy current losses because of high electric resistivity of the ferrite substrate.
