  • Patent number: 6335908
    Abstract: A magneto-optical recording medium includes a transparent substrate, an underlying layer, a reproducing layer, a mask layer, a recording layer, and a protection layer. Reproducing layer is an in-plane magnetization film at room temperature and is transformed into a perpendicular magnetization film at about 150° C. Mask layer is an in-plane magnetization film at room temperature and reaches the Curie temperature around 140° C. which is lower than the reproducing temperature. Only the region whose temperature has reached the Curie temperature is demagnetized, and the other region retains the in-plane magnetization. The width of region whose temperature reaches the Curie temperature is substantially equal to the shortest domain length of recording layer. The magnetic domain of recording layer is transferred to reproducing layer 3 through the demagnetized region of mask layer.

  • Patent number: 6334186
    Abstract: A digital video disk controller for reading data from an optical disk and stores the data in a memory. The data is then read from the memory and encrypted by an arithmetic processor. The encrypted data is then transmitted directly to an external device, via an interface circuit, without first storing the encrypted data back into the memory. The number of memory accesses performed by the controller is thus reduced, providing for lower power dissipation and faster access to the read data.
