Abstract
A combined eraser and splice finder for an NAB tape cartridge which comprises apparatus for subjecting an NAB tape cartridge to an initially strong and thereafter diminishing and vanishing oscillating magnetic field for bulk tape erasure and which, independently or at the termination of the erasure cycle, also senses the presence of the tape splice and stops tape travel within the cartridge at a point where subsequent recording can begin immediately behind the splice. The apparatus is capable of erasure without splice-finding or splice-finding without erasure.
