In a disk stand device and a disk storage device for use in compact disks, mini disks and floppy disks, an array of grooves (2) are provided on an upper surface of a pedestal (1) at predetermined intervals (L). When one end of a disk (3) is inserted into the groove (2) upon accommodating the disks (3), a plurality of disks (3) are positioned to overlap with the predetermined intervals (L) therebetween. A title labelled on the disk (3) can be visually recognized through the intervals (L) of the neighboring disks (3). Upon reusing the disk (3), the disk (3) can be taken out of the groove (2) quicky to improve an efficiency at offices in which electronic computers are employed.
