Abstract

PURPOSE: To protect discs and heads by providing a film composed of α-Fe2O3 on magnetic recording medium surfaces used by contact start-stop system.
CONSTITUTION: A film of α-Fe2O3 is formed on magnetic recording medium surfaces by using, e.g., sputtering method. The thickness of said film is desirably about 0.2μ or under with recording media for which recording density is not so critical and about 0.1μ or under with those for which high density recording is critical. Provision of the abovementioned film reduces the attraction force between head and disc, reduces the gimbal deformations of heads and improves the occurrence of abrasion and scratching of discs and heads.
