Apparatus for recording or playing back information magnetically recorded on a tape or web having a recording width of five inches or more for the purpose of handling recordings of long duration, such as books. The apparatus includes means for intermittent incremental advance of the web from the feed spool to the take-up spool, and means for producing traversal of the record-playback heads transversely across the web relative to adjacent, parallel, transverse tracks on the web. In one form, a head reciprocates back and forth to produce one or more tracks between each incremental web advance. In another form, heads carried on a rotor produce two or more adjacent tracks in the same direction between each incremental advance of the web. The apparatus includes means for rapid advance and rewind of the web.
