ABSTRACT:
A recording apparatus for recording data in a thermosensitive recording medium. The recording medium has a reversible thermosensitive recording material capable of selectively assuming one of two visible states, e.g., a cloudy state and a transparent state or a colored state and a decolored state when heated. The thermosensitive material is applied to a sheet of resin. The apparatus surely erases data written in the medium with no regard to the time elapsed and the number of times that data has been repetitively written. The cloud density or the color density is prevented from changing with no regard to the storage temperature, the time elapsed, or the number of times of writing, thereby preventing image quality from being degraded. In addition, the medium has a long service life.
