Abstract
A porous impregnation material (14) impregnated with a gaseous-phase lubricant that vaporizes at an atmosphere temperature within an outer case (2) is disposed in the inside of the outer case (2) that incorporates a tape mechanism (1) having a magnetic head such as a rotary video head (5). This allows the magnetic head to be in a state of being protected by a coating film of the gaseous-phase lubricant, thereby eliminating the adhesion of foreign substances other than the gaseous-phase lubricant to the magnetic head. As a result, decrease in the reading precision of magnetic data to be caused by the foreign substances can be prevented.
