Abstract
A disk laminate includes thin disks laminated to each other, which are to be suctioned and conveyed; and spacers provided between the thin disks to prevent the thin disks from directly contacting each other, the spacers having air permeability.
Claims22
A disk laminate comprising:
- thin disks laminated to each other, which are to be suctioned and conveyed;
- and
- spacers provided between the thin disks to prevent the thin disks from directly contacting each other, the spacers having air permeability.
A disk loading/unloading mechanism for loading and unloading a thin disk to and from a disk cartridge, the disk cartridge including a disk tray on which the thin disk is placed, the disk tray being drawn out from and put into the disk cartridge, the disk tray having an opening at a center part thereof, the disk loading/unloading mechanism comprising:
- an elevating mechanism including an elevating shaft being movable up and down through the opening so that part of a leading edge of the elevating shaft can be inserted into a center hole of the thin disk, the elevating mechanism being positioned below the opening of the disk tray when the disk tray is drawn out;
- and
- a disk holding mechanism including a holding member that holds the thin disk and a supporting shaft that supports the holding member, the supporting shaft being parallel to the elevating shaft, wherein a central axis of the supporting shaft and a central axis of the elevating shaft correspond to each other when the holding member is positioned above the disk tray.
A disk conveying mechanism used in a thin disk driving system including a disk cartridge and drive devices, the disk cartridge storing a disk laminate formed of thin disks, and the drive devices performing at least reproducing of the thin disks among reproducing and recording, the disk conveying mechanism comprising:
- holding mechanisms that hold the thin disks;
- arms having first ends to which the holding mechanisms are attached and second ends that are fixed to a rotational shaft;
- and
- an actuating device that rotates the rotating shaft, wherein
- the rotational shaft is provided at a position such that a center of the disk laminate and centers of drive trays drawn out from the drive devices are arranged along the same circumference centered at the rotational shaft with intervals of equal center angles, and
- the center angles are equal to at least one of center angles between the arms.
A disk conveying mechanism used in a thin disk driving system including a disk cartridge and drive devices, the disk cartridge storing a disk laminate formed of thin disks and spacers provided between the thin disks, and the drive devices performing at least reproducing of the thin disks among reproducing and recording, the disk conveying mechanism comprising:
- holding mechanisms that hold the thin disks;
- a spacer stocker on which the spacers are temporarily placed;
- arms having first ends to which the holding mechanisms are attached and second ends that are fixed to a rotational shaft;
- and
- an actuating device that rotates the rotating shaft, wherein
- the rotational shaft is provided at a position such that a center of the disk laminate, a center of the spacer stocker, and centers of drive trays drawn out from the drive devices are arranged along the same circumference centered at the rotational shaft with intervals of equal center angles, and
- the center angles are equal to at least one of center angles between the arms.
