Abstract: An apparatus and a method, which make it possible to collect a plurality of the contents authored for DVD to record easily them on a large-capacity information record medium and to increase a data rate in reproducing the recorded contents, perform the processes of: creating source packets from a disk image file; collecting them to form arrangement units 320; collecting them to form ECC clusters; collecting sectors of the DVD to form a sector group, thereby storing it while bringing it into correspondence with a predetermined number of source packets; adding a control packet to this to form units of conversion; collecting them to bring them into correspondence with an integral number of the arrangement units 320; and storing a cluster-number, at which a leading sector of the sector group of the DVD is stored in the control packet; wherein the source packets are brought into correspondence so that a leading portion of the file system area coincides with both a leading portion of the arrangement unit and a leadi

Abstract: A housing capable of being carried into an elevator cage and turned with ease even in the elevator cage having a narrow frontage is provided. A housing 1 is configured to have a dimension A of a first face narrower than an effective doorway dimension a of an elevator cage 20, and a dimension B of a second face wider than an effective depth b of the elevator cage 20, and corner portions are chamfered in an up and down direction, and the chamfered dimension X is set to a value obtained by subtracting the effective depth b of the elevator cage 20 from the dimension B of the second face. Further, the corner portions may be chamfered in a same shape. In addition, each of the corner portions is chamfered to have an angle of approximately 45 degrees in relation to an adjoining surface.
