Abstract
Abstract A flexible, elongated, easily insertable and extractable cassette recording/erasing device with inwardly extending end portions that are receivable within the erase openings of the cassette so that the device can perform the functions of the record and erase tabs on the rear edges of standard commercial cassettes. Between the end portions, the device may be provided with a laterally outwardly extending section on each side thereof from which walls extend in spaced, generally parallel relation in the same direction as the end portions. The walls engage opposite sides of the cassette to removably retain the device on the cassette when the end portions are positioned in the erase openings of the cassette.
