Title: Magneto-optical recording medium and method for reproducing the same
Inventor: TANI MANABU
IPC: G11B11/105
Filed: 2002-10-30
Abstract: <P>PROBLEM TO BE SOLVED: To provide a magneto-optical recording medium which can prevent the generation of a ghost signal and in which magnetic domains can be expanded for reproduction without applying reproducing magnetic fields and to provide a recording and reproducing device for the same.  <P>SOLUTION: The magneto-optical recording medium is provided with a recording layer 5, an intermediate layer 4, and a reproducing layer 3. The reproducing layer 3 is formed of a rare earth metal-dominant rare earth transition metal alloy, and the intermediate layer 4 and the recording layer 5 are formed of transition metal-dominant rare earth transition metal alloys. The intermediate layer 4 exhibits longitudinal magnetization at ≥140°C and therefore shuts off exchange coupling forces of the recording layer 5 and the reproducing layer 3 during reproduction. The magnetic domain 3A transferred to the reproducing layer 3 is expanded to the size of a minimum magnetic domain diameter by magnetostatic repulsions of the intermediate layer 4 and the reproducing layer. The generation of the ghost signal can be prevented.  <P>COPYRIGHT: (C)2004,JPO

Title: Method, apparatus and program for encoding multi-band video signal and recording medium with the program recorded thereon
Inventor: TAKAMURA MASAYUKI
IPC: H04N1/41
Filed: 2002-11-06
Abstract: <P>PROBLEM TO BE SOLVED: To provide a scalability function when a multi-band video signal is encoded.  <P>SOLUTION: An N band video signal being an object of processing is separated into a visible signal of three bands and an invisible signal of N-3 band by using linear transformation. The separated visible signal is transformed (is non-linearly transformed in uniform color space, for example), and a principal component of the separated invisible signal is transformed. The band of low contribution is removed from an object of encoding in the invisible signal after the principal component is transformed. While the transformed visible signal and the invisible signal being the object of encoding are encoded in an independent form, monochrome pictures of the signals are encoded and an encoded result is multiplexed. Since constitution where a code amount of the visible signal and the invisible signal can freely be changed is adopted, various encoding modes can be selected. Thus, the scalability function can be given.  <P>COPYRIGHT: (C)2004,JPO
