ABSTRACT:
This invention relates to a pad abutting device for a magnetic head of a dual capstan type cassette tape recorder. This pad abutting device comprises a pair of upper and lower abutting members mounted on a front face of a magnetic head which is to be extended through an opening of a cassette having a pad provided therein, the abutting members being disposed apart by a distance less than the width of the pad, but greater than the width of a magnetic tape in the cassette. When the cassette is placed in the tape recorder so that the magnetic head enters the opening of the cassette, the abutting members abut against the pad at its upper and lower edges whereby the pad is prevented from resiliently pressing the magnetic tape against the magnetic head. Each of the pad abutting members comprises a spacer provided integrally with the body of the respective pad abutting member, disposed between the body of the pad abutting member and the front face of the magnetic head so as to abut against the latter, the spacers of the abutting members having a thickness greater than that of the magnetic tape, respectively and being disposed apart by a distance substantially greater than the space between the upper and lower abutting members.
