摘要：A method of reading out data from a domain expansion data storage such as aMAMMOS magneto-optic disk () which includes a data storage layer in which data is

stored in the form of magnetic marks, and an expansion layer capable of copying andexpanding domains from the storage layer, the system applying a first radiation beam (),having a first spot size on the disk, in order to initiate copying of a domain from thestorage layer to the expansion layer, and applying a second radiation beam (), having asecond spot size larger than the first spot size on the disk, in order to read out data fromthe expansion layer.
