ABSTRACT:
An apparatus for recording and reproducing a tape-shaped recording medium, which is capable of minimizing the effect of adsorbed water present at the interface between the tape and a sliding member and hence enables the tape to travel stably without sticking to the sliding member even under conditions close to moisture condensational conditions. An aluminum alloy is employed as a material for a sliding member such as a fixed drum, stationary tape guides, etc. on which a video tape slides, and a large number of projections are formed on the surface of the sliding member. A material of high water repellency is formed on the surface of the sliding member for the purpose of minimizing the effect of contact portions formed by the video tape and the projections of the sliding member and the effect of bonded portions of adsorbed water produced around the contact portions (at the interface). More specifically, the surface of the sliding member is formed with an electrolessly plated nickel film containing polytetrafluoroethylene particles.
