Abstract

This paper reports the properties of antireflection structure and hole formation of Te-based systems. The optical-recording characteristics of metallic recording media are enhanced significantly by incorporating the metal(Al) layer into an antreflection trilayer structure. Due to the interface condition inherent in the design of the trilayer structure, reflectivity from holes is ranked low fraction (<10%). The hole formation is carried by $Ar^+$ Laser(488nm). For 20nsec pulse duration, hole opening power(threschold) of $(Te_{86}Se_{14})_{50}Bi_{50}$ trilayer is lower than that of monolayer that used in this experiment. Hole shapes of the whole sample were clean.
