Rotary transformer for a recorder

摘要

In the case of a rotary transformer for the rotating head drum of a recorder, having a plurality of heads, it is intended in particular for the recording of digital signals to achieve a high crosstalk attenuation between the pairs of windings (3, 6) of the individual heads. The windings (3, 6) are arranged on a carrier (2, 5) of ferrite and between the carriers (2, 5) there lies in each case a separating film (7) of a magnetically inactive material. In particular for a recorder having a plurality of heads for a matrix-like recording of digital signals. <IMAGE>
