  • Magnetic recording and reproducing apparatus of rotary head type
    Patent number: 4789912
    Abstract: A magnetic recording and reproducing apparatus of rotary head type such as a rotatable video tape recorder has a tape guide for guiding the magnetic tape when the tape runs on and around a cylinder carrying rotary heads. A tape loading movable member carries the tape guide. A tape loading drive is provided for driving the tape loading movable member so as to move the tape guide between a tape loading position where it places the magnetic tape in contact with the cylinder through a predetermined angle and an unloading position where it keeps the magnetic tape away from the cylinder. A locating unit is provided on at least one of the cylinder and a cylinder base carrying the cylinder. The locating unit is adapted for engaging with the tape loading movable member in the tape loading position so as to locate the tape guide with respect to the cylinder.
