PURPOSE:To prevent a disk from being scratched when the disk is inserted into a disk mounting device by forming a triangular-shaped guide groove inserting and guiding the disk to have an arc-shaped form and holding the disk by means of an edge section having no relation with the characteristic of the disk. CONSTITUTION:The triangular-shaped guide groove 11, inserting and guiding the disk is formed in a disk holding member 9, which holds the disk 2, of a disk mounting device to have the arc-shaped form and the disk 2 is held by means of an edge section having no relation with the characteristic of the disk 2. Therefore, the disk is prevented from being scratched at the time of insertion and, at the same time, since more than half of the disk is held by the arc-shaped guide groove 11, the disk is reliably secured. Consequently, a device utilizing this constitution can be used suitably for a device on-vehicle accompanying vibration. |
