Abstract

In record storage disk apparatus, it is often desirable to have radially outward air flow over the record disks. In some apparatus, central arbor 10 has a fluid communication passageway to plural connections about its circumference to provide air flow from a source, not shown. In a spaced disk assembly, it is desirable to have air flow circumferentially uniform which also provides a low-cost, disk pack assembly.

Disk Pack Assembly

In record storage disk apparatus, it is often desirable to have radially outward air flow over the record disks. In some apparatus, central arbor 10 has a fluid communication passageway to plural connections about its circumference to provide air flow from a source, not shown. In a spaced disk assembly, it is desirable to have air flow circumferentially uniform which also provides a low- cost, disk pack assembly.

In accordance with this teaching, the spacing between adjacent record disks is formed by bent-over tabs punched or otherwise cut from a radial inward portion of each record disk. Adjacent disks are spaced apart by the tabs. The tab forms the air passages 11 which axially extend the entire length of arbor 10. The air from these passageways then flows outwardly between the tabs, to provide a uniform air flow between each of the adjacent record disks.
