Zusammenfassung:	1344770 Magnetic records CONTROL DATA CORP 16 May 1972 [3 June 1971] 22839/72 Heading G5R [Also in Division C7] A magnetic recording medium for high density magnetic recording systems comprises an Al or Al alloy disc 20, a Zn coating 21, a Ni-P layer 22, a Au layer 23 >125 thick and a Co-P layer 24. All the coating layers are deposited by electroless deposition (see Division C7). The Co-P layer is < 10,000 thick, has an intrinsic coercivity of at least 300 Oe., and a ratio intrinsic coercivity to saturation coercivity of at least 0À95.
