Abstract

An automatic load system for rigid disk cartridges is described. The disks are stacked in a magazine which is pivoted to different indexed positions to allow individual cartridges to be withdrawn. A cartridge receiver adjacent to the magazine is also pivoted and is mechanically linked with the magazine so that it is co-planar with each individual cartridge at the respective index position when a cartridge is to be loaded or unloaded by a belt drive. The cartridge receiver includes a disk drive which is automatically loaded or unloaded. Figs. 1 and 2 illustrate the automatic load system which includes a magazine to hold five disk cartridges in a stack which may be inserted into a magazine holder adjacent to the cartridge receiver.

Automatic Load System for Disk Cartridges

An automatic load system for rigid disk cartridges is described. The disks are stacked in a magazine which is pivoted to different indexed positions to allow individual cartridges to be withdrawn. A cartridge receiver adjacent to the magazine is also pivoted and is mechanically linked with the magazine so that it is co-planar with each individual cartridge at the respective index position when a cartridge is to be loaded or unloaded by a belt drive. The cartridge receiver includes a disk drive which is automatically loaded or unloaded. Figs. 1 and 2 illustrate the automatic load system which includes a magazine to hold five disk cartridges in a stack which may be inserted into a magazine holder adjacent to the cartridge receiver. Under automatic control the magazine is indexed to a selected one of five cartridge positions, the selected cartridge withdrawn from the magazine into guides, and the disk drive in the cartridge receiver loaded. The rear of the cartridge receiver is attached to a base casting by receiver pivots while the front of the magazine holder is attached to the same base casting by magazine pivots. The two pivoted assemblies are mechanically linked by a rocking link so that they rotate in the same direction about their pivots; i.e., when the rear end of the magazine holder is raised, the front of the cartridge receiver is lowered. As illustrated in Fig. 2, the geometry of the pivots and rocking link is designed to maintain an almost constant gap between the adjacent ends of the magazine holder and cartridge receiver. The cartridge r...
