Title: Magnetic recording medium
Inventor: ICHIKAWA KOJI
IPC: G11B5/66
Filed: 1989-09-14
Abstract: PURPOSE:To provide the recording medium which has excellent corrosion resistance, is small in bit shift and is large in residual magnetization by forming a magnetic film of an alloy consisting, by atomic %, of 5.0 to 15.0% Cr, 2.0 to 8.0% one kind selected from a group of Zr, Ti, Hf, and Mo and the balance Co. CONSTITUTION:The magnetic film is formed of the alloy consisting, by atomic %, of 5.0 to 15.0% Cr, 2.0 to 8.0% one kind selected form Zr, Ti, Hf, and Mo and the balance Co, and unavoidable impurities. The corrosion resistance degrades if the content of the Cr is below 5.0atomic%. Namely, the rate of decrease in the saturation magnetization by an environmental change is large and the bit shift is increased. On the other hand, the degradation in output is resulted from a decrease in the residual magnetization and the increase in the bit shift is resulted as well if the content of the Cr exceeds 15.0atomic%. The Zr, Ti, Hf, and Mo contribute to the improvement in the bit shift characteristics but this effect cannot be expected if the content thereof is below 2.0atomic%. On the other hand, the bit shift increases if the content thereof exceeds 8.0atomic% and, therefore, such ratio is undesirable. The particularly excellent corrosion resistance is obtd. in this way and the bit shift and residual magnetization characteristics are improved as well.
