Abstract

A disk file employs a stack of disks 10, each disk being contained in a disk tray 12. The tray serves as a holder-spacer for the flexible disk while the disk 10 is contained in the stack, and as a holder during transport of the disk between the stack and a selected rotary spindle 16; and also acts as a stationary support for the disk 10 while it is being rotated by the spindle. The disk trays 12 are arranged in the stack and are accessible by an access jaw 14, which is disposed adjacent to the stack of disks 10. The access jaw can be rotated to carry a selected disk tray 12 between the stack and any one of the rotary spindles 16. The access jaw can be clamped and unclamped from a tray to accomplish transport.

Floppy Disk File

A disk file employs a stack of disks 10, each disk being contained in a disk tray 12. The tray serves as a holder-spacer for the flexible disk while the disk 10 is contained in the stack, and as a holder during transport of the disk between the stack and a selected rotary spindle 16; and also acts as a stationary support for the disk 10 while it is being rotated by the spindle. The disk trays 12 are arranged in the stack and are accessible by an access jaw 14, which is disposed adjacent to the stack of disks 10. The access jaw can be rotated to carry a selected disk tray 12 between the stack and any one of the rotary spindles 16. The access jaw can be clamped and unclamped from a tray to accomplish transport.

For selecting a disk, the stack is moved vertically or axially so that the desired disk is at the operating level relative to the access jaw 14. During rotation of a disk 10 on the spindle 16, a clamp solenoid 18 is used to hold the disk to the spindle. A separate accessing read/ write head 20 is available for each spindle and accesses the selected disk through a slot 22 in the tray.
