PCT No. PCT/DE88/00052 Sec. 371 Date Oct. 13, 1988 Sec. 102(e) Date Oct. 13, 1988 PCT Filed Feb. 3, 1988 PCT Pub. No. WO88/06782 PCT Pub. Date Sep. 7, 1988.To assure production of compatible magnetic tracks on magnetic tape, the head wheels of oblique-track tape decks must be height-adjustable. In conventional devices, adjustment of the head wheel height alters the pre-tensioning of the head wheel bearings or the length of the tape loop around the playback device must be chosen unnecessarily large. In the playback device of the present invention, the head wheel motor and head wheel form a unit which is axially shiftable. The pre-tensioning of the bearings is accomplished using a spring device which is supported against an element which rotates with the head wheel axle.
