Abstract

A scanning device for a magnetic tape recording and playback equipment of the oblique track type has a drive shaft (9) for a rotary head wheel (4) mounted in a duplex ball bearing (10) centered on the orbit plane of the magnetic heads which revolve on the circumference of the head wheel between the two halves of a tape-guiding drum. A support bearing (19) is affixed in the bottom of a housing (17) which houses the drive motor and is held in a downward extending socket at the bottom of the lower half of the drum. The housing can be tilt-shifted slightly for shifting the support bearing and then held, by three screws accessible from below, in the correct position for aligning the orbit of the magnetic heads in the gap between the two halves of the drum.
