ABSTRACT:
An improvement in a magnetic tape cleaner apparatus that includes supply reel, take-up reel, wiper for wiping the tape, winder and rewinder for moving the tape between the respective reels, the improvement being characterized by a scraper blade for scrapingly engaging the tape for removing debris therefrom for improving subsequent tape-to-head contact and a holder and ultrasonic vibrator for ultrasonically transducing the scraper blade as it is scrapingly engaging the tape before efficiently removing the debris such that subsequent tape-to-head contact is improved. Specific preferred embodiments include one in which there is provided an automatic rewind for sensing when the tape is wound onto the take-up reel sufficiently and automatically rewinding it past the scraper blade being ultrasonically transduced for the more effective cleaning action as it is rewound onto the supply spool; where packing wheel is provided for removing air between the windings of the tape on the supply reel and where a particular apparatus and angles of contact are delineated.
