A finite conjugate, high numerical aperture objective configured with a compensating telescope was designed to read and write in multiple layer optical disk storage system. The system was capable of focusing onto individual data layers with high numerical aperture and good field performance. A number of finite conjugate aberration compensation systems was investigated. The results showed that a Burch-type objective lens in conjuction with a Galilean telescope was a compact, simple and effective optical system for spherical aberration compensation.
