Abstract
Abstract Apparatus for transverse recording across a moving magnetic tape. The tape is moved in the direction of its length through a guide which is reciprocated in a direction parallel to the plane of the tape and perpendicular to the length of the tape. The magnetic head is also reciprocated in a direction parallel to the plane of the tape but in opposition to the direction of the guide.

Total Claims: 3
Claim 1
Independent Claim
95 words
In a recorder, the improvement comprising: means for moving a recording medium past a recording head in a first direction; means for simultaneously moving said recording head in a second direction perpendicular to said first direction and in the plane of the recording medium, so that the relative motion between said recording medium and said recording head describes a sinusoidal path on said recording medium; a stationary recording head for recording a synchronizing track on said recording medium; and means for moving said recording medium in a direction parallel and opposite to said second direction.
