Magnetic recording medium containing an unsaturated fatty acid diester of a dihydric alcohol |
摘要 |
A magnetic recording medium has a magnetic layer on a non-magnetic substrate. The magnetic layer contains ferromagnetic powder dispersed in a binder and a lubricant which is an unsaturated fatty acid diester of a dihydric alcohol and an unsaturated fatty acid, preferably a C2-6 dihydric alcohol and a C14-24 unsaturated fatty acid, typically neopentyl glycol dioleate. The lubricant remains effective in low-temperature, high-temperature, and thermal cycling environments without bleed-out. The medium is low in rotational torque, abrasion resistant and durable.
