Abstract:
1. A recording and/or reproducing device for recording and/or reproducing information on a tape-shaped data carrier, said data carrier extending in a direction of tape travel and being capable of being moved forward in the direction of tape travel, said recording and/or reproducing device comprising a magnetic head for scanning the data carrier, and at least one tape guide, said tape guide guiding the data carrier past the magnetic head, and comprising a curved guide wall and two guide flanges projecting beyond the guide wall, said two guide flanges having mutually facing delimiting walls adjoining the guide wall, said tape guide having a transitional area between the guide wall and each of the two guide flanges, the sections of the tape guide located in the two transitional areas exerting, on the delimiting edges of the data carrier, a force that counteracts an incorrect movement of the data carrier occurring perpendicularly to the direction of tape travel, wherein at least the guide wall and the two guide flanges of the tape guide are composed of a material suitable for retaining a coating, wherein at least said sections of the tape guide located in the two transitional areas that exert the counteracting force on the delimiting edges of the data carrier are coated with a coating, said coating having a surface hardness of at least 2200 HV, a surface tension of not more than 40 mN/m and not containing chromium, and wherein the coating is composed of zirconium nitride or titanium nitride.
