ABSTRACT OF THE DISCLOSURE A guide drum apparatus for a video tape recorder and/ or player has a main shaft secured on a chassis, a first guide drum rotatably mounted on the main shaft and having a plur- ality of magnetic video heads, driving means for rotating the first guide drum at a rotational speed greater than the speed of movement of a tape, and a second guide drum mounted on the main shaft coaxially with the first guide drum and rotatable independently therefrom. The first and second guide drums have tape guiding portions, respectively, which are opposed to each other and have peripheral tape guide surfaces to guide the magnetic tape. Adjusting means is mounted on the main shaft so as to adjust the height of the video heads with respect to the tape guiding portion of the second guide drum. With this guide drum apparatus, the height of the video heads can be adjusted precisely and easily to trace the video track on the tape, even while the video heads are rotating at a high speed.
