Abstract
A cassette indicating mechanism is disclosed for a cassette of the type having top and bottom halves and an information recording medium interposed therebetween. The indicating mechanism indicates whether information can or cannot be recorded on the recording medium. The cassette indicating mechanism is in a normal recording position in which a colored portion thereof is visible and preferably blocks an interfacing detector of a recording device. The blocked detector actuates the recording device to permit recording on the recording medium. The indicating mechanism is movable to a non-recording position in which the colored portion is hidden and the interfacing detector of the recording device is preferably unblocked. The unblocked detector actuates the recording device to prevent recording on the recording medium.
