A magnetic tape loading device comprises a head drum having magnetic heads, a drum base supporting the head drum, two loading rings supported on an upper surface of a chassis and rotatable in opposite directions, two tape guide blocks having guide posts for pulling out a magnetic tape from a tape cassette and winding it on the head drum, and guide block guide members for guiding the block. The loading rings are vertically spaced in coaxial relation at the outside of the drum base. The tape guide block is supported on the guide block guide members to be movable along a path slanted with respect to the two loading rings and is coupled to the lower loading ring by a connector mechanism, and the tape guide block is coupled to the upper loading ring, so that the two tape guide blocks are movable in opposite directions around a periphery of the head drum in response to rotation of the two loading rings for winding the tape helically on the periphery of the head drum over an angle of contact with the head drum of at least 300 DEG and with a spacing between the beginning and end of a portion of the tape that contacts the head drum corresponding substantially to the width of the tape. |
