    摘要: A hologram disc reading and writing apparatus including a signal light source module, a beam splitter, a reference/reading light source, a reflector, and an optical reading head and a hologram disc reading apparatus are provided. A signal light beam emitted from the signal light source module is transmitted to a data region of a hologram disc through the beam splitter. The reference/reading light source, the signal light source module, and the optical reading head are disposed at the same side of the hologram disc. The reflector is disposed at the other side. A spherical wave light beam emitted from the reference/reading light source is transmitted through the data region and reflected by the reflector to form a phase conjugate light beam transmitted to and through the data region. The phase conjugate light beam is transformed to a data light beam transmitted to the optical reading head through the beam splitter.
