Abstract:
A high data density optical recording medium, a method and an apparatus for reading such an optical recording medium, and a method for mastering such an optical recording medium are proposed. For achieving a high data density the optical recording medium has marks that have a tip and are covered by a material that generates a detectable effect under the influence of high electric fields.
