Controlling an information recording apparatus for recording information in a detachable, re-writable storage medium which has a storage size exceeding a maximum allowable size of a first file system. The light-condensing layer includes a plurality of focusing elements for focusing incident sunlight and a plurality of corresponding collimating elements for collimating the light for output to the optical waveguide layer. The source contact is connected to both source and channel regions for a unidirectional conduction device, or only to the source regions for a bidirectional device.
