摘要： An erasable optical recording element is provided having a supporting plate which comprises a recording layer which has a Te-Se-Sb alloy. The ratio of the elements Te, Se and Sb in at.percent lies within a range in the Te-Se-Sb composition diagram which is bounded by a polygon having the corners Te 90 Se 8 Sb 2 - Te 78 Se 20 Sb 2 - Te 18 Se 52 Sb 30 - Te 28 Se 2 Sb 70 - Te 90 Se 2 Sb 80 . The layer thickness of the recording layer is between 80 and 300 nm. During recording the recording layer is converted by exposure to modulated laser light in the exposed places from a more ordered or crystalline state into a less ordered or amorphous state. The locally changed state can be read by means of laser light. A method of recording information is also described.
