摘要: Disclosed is an information storage medium having an air-sandwich structure which comprises two disc-shaped substrates joined together through a ring-shaped inner spacer and a ring-shaped outer spacer. These spacers are made of the same kind of resin as those forming the disc substrates and the resin of the spacers has a viscosity-average molecular weight larger than that of the resin of the substrates. Also disclosed is a process for producing the information storage medium by joining the spacers to the disc substrates by means of ultrasonic welding.
