ABSTRACT:
In a recording and/or reproducing apparatus for a magnetizable tape, such as a VCR, having a cylindrical scanning unit about which a length of tape can be wrapped, electromagnetic shielding is provided by a shielding enclosure for the scanning unit and a shielding box for an amplifier connected to the unit by a shielded cable. The shielding box and the shielding enclosure share a common wall portion arranged between the scanning unit and the amplifier. The common wall portion is preferably arranged perpendicular to the cylindrical scanning unit axis, and has an end of the scanning unit shaft passing through an opening for engagement by a leaf spring connected to the common wall portion.
