摘要： To effectively eliminate cross-talk between the weak signals picked up by a tape transducer pick-up head with signals being applied to a recording head, a disk-like headwheel carrier has a disk-like headwheel secured thereto. The disk-like headwheel carrier is formed with a recess which defines a chamber (6) in which the preamplifier for the reproduced signals is placed. Transducer leads are passsed in a channel duct formed between the headwheel carrier and the disk-like headwheel, which is in plate form. Preferably, both the disk-like headwheel as well as the carrier are made of lightweight metal, such as aluminum, so that the reproducing amplifier is totally shielded. The recording amplifier can be placed on top of the disk-like headwheel, separated and shielded from the reproducing preamplifier.

摘要： 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.

摘要： The elongated drum guide (1), on which the two drum-shaped parts of the drum arrangement around which a magnetic tape is guided in one helical turn are held in place, has pairs of seating ribs running circumferentially in a cylinder-arc cavity for seating the two drum parts in the proper alignment and at the proper spacing from each other to allow a head wheel to revolve in the slot between the parts (2, 3) Screws (20) pass through the drum guide (1) and through the seating ribs for holding the drum parts in place in such a way as to provide no strains producing long-term deformation, while at the same time assuring precision of reassembly after demounting the scanning device for replacing the magnet heads of the head wheel. The drum guide is made of a light metal alloy and the seating surfaces of the internal ribs are machined by electric spark erosion to provide the necessary precision and also a hardening of the surface.
