Abstract: <P>PROBLEM TO BE SOLVED: To miniaturize an optical pickup device for hologram recording.  <P>SOLUTION: A space light modulator 16 has a plurality of pixels, and can change the intensity of incident light at a pixel unit. A polarization beam splitter (PBS) 30 separates an output laser beam of a laser device 40 into a S polarization component and a P polarization component, and supplies the one component to the space light modulator 16 through a 1/4 wavelength plate 20 and supplies the other component to a whole reflection mirror 38 through a 1/4 wavelength plate 36. The PBS 30 composites information light from the space light modulator 16 and reference light from the whole reflection mirror 38, and supplies it to a rotary polarization plate 32. The rotary polarization plate 32 comprises a right rotary polarization plate 32R rotating the polarization of incident light at 45 degrees clockwise, and a left rotary polarization plate 32L rotating the polarization of the incident light at 45 degrees counterclockwise. The rotary polarization plate 32 generates polarization components being the same each other from the inputted information light and the reference light. An object lens 34 converges light from the rotary polarization plate 32 to a disk recording medium 12.  <P>COPYRIGHT: (C)2004,JPO

Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for making a digital system, com prising plural processors 102, 104 connected to a shared memory subsystem 112 and peripheral devices 106, 116 operate. SOLUTION: Plural processors execute different operating systems, and a system protection map (SPM) defines a pair of address space region in the address space of a memory subsystem, assigns a resource access rights, for at least a part of the pair of address space regions, and displays which originating resource can be made to access each region. When the address contained in an access request is used, SPM identifies the region being accessed by the memory access request. In each access request, SPM identifies the origination of the request, by using the resource identifier value (R-ID) of the request and decides whether the resource accessing the identified region possesses the access rights for the region. Only when the resource possesses the access rights for the identified region, SPM permits access to the identified region.
