Paper Abstract

For high density optical recording requiring a high numerical aperture objective, it has been found that substrate incident recording suffers from spherical aberration because of substrate thickness variations. To overcome this problem a novel protective cartridge-enclosed disc has been developed which provides the advantages of air incident recording without the presence of spherical aberration. This cartridge protects the disc from atmospheric dust and virtually eliminates the possibility of internal dust generation both during operation and during storage. In addition, all components, including dust seals, have an expected life of at least 10 years. Key optical and mechanical considerations are discussed as well as experimental results obtained from an operational prototype.
