Beschreibung
Zusammenfassung:	An information recording apparatus, includes a semiconductor light source responsive to an information signal to be recorded to produce information light; a photosensitive member for receiving the information light produced by said semiconductor light source; a driver for supplying to said semiconductor light source an electric current I0 having a current level lower than a light emitting threshold current Ith of said semiconductor light source before said semiconductor light source is driven in accordance with the information signal to be recorded, so that said semiconductor light source heats itself by the application of the current I0. Thus when the apparatus is in a stand-by state, the semicondcutor light source is supplied with an electric current which has a lower level than the threshold level, so that the semiconductor light source is self-heated due to the low level current.
