초록 ▼

A disk-jacket assembly including a flexible disk rotatably disposed in a square jacket having radially extending registering slots in its two thicknesses for receiving a pair of opposite transducers or alternately a single transducer in one slot and a pressure member in the other slot. Panels of porous low friction dusting fabric are disposed between the faces of the disk and the opposite inner faces of the jacket. The dusting fabric has slots coincident with the slots in the jacket, and the dusting fabric slots are wider than the jacket slots particularly for spacing the disk entry side edges of the jacket slots from the adjacent edges of the fabric to substantially prevent loose fibers on the fabric extending into the jacket slots.

대표청구항 ▼

In a magnetic record assembly including a magnetic disk of thin flexible material; a jacket having said magnetic disk disposed therein and having panels of a porous, low friction, dusting fabric lining positioned between and adhered to opposite, confronting faces of said jacket and covering substantially all the jacket surface confronting said magnetic disk to line said jacket for snugly encasing said disk and allowing the disk to be rotatably driven within the jacket; and an elongated opening in said jacket and a gap in said panels having edges that register with said jacket opening so that said opening may receive a magnetic transducer in data transferring relationship with said disk; the improvement wherein the side edge of said jacket opening and the edge at the panel gap adjacent to which increments of said disk first appear due to rotation of the disk are spaced from each other with the disk entry side edge of said fabric panel gap being positioned upstream of disk rotation with respect to the disk entry side edge of said jacket opening, whereby said disk is substantially continuously wiped by said panels while providing a space between said fabric and said jacket opening which excludes frayed or free fibers from the jacket opening.
