Document Type and Number:

Japanese Patent JP3187111

Kind Code:

B2

Abstract:

For oblique track scanning of magnetic tape which is looped around a two-part drum (1, 2) separated by a gap (5) in which magnetic heads (11) affixed to a headwheel revolve, the rotary transformers connecting the magnetic heads on the headwheel to fixed parts of the scanning device are provided by inner and outer magnetic core rings in which windings are embedded for a number of transformers. One group of these rotary transformers (18, 19) is located above the headwheel disk structure (10, 25) in such a way that outer magnetic core rings are fixed in a bore of the fixed upper drum (1) and inner magnetic core rings (19) are affixed to a seating shell (25) that connects the headwheel disk (10) to its driving shaft. Another group of rotary transformers (10, 21) is located beneath the rotary headwheel disk structure (10, 25) and in this case the outer magnetic core rings (20) are affixed to the inner wall of the rotary headwheel disk structure (10, 25) and the inner magnetic core rings are affixed to the outer wall of the bearing (15) of the shaft (14) that drives the rotary headwheel disk.
