Abstract

The edge surfaces of magnetic recording tape are cleaned by subjecting the edges to the brushing action of edge guides, while at the same time scraping the polyester surface adjacent the edges, and then removing the scraped-off debris by use of a vacuum source. Tape 10 is about one-half inch wide, and is made up of a flexible substrate 12 on which a magnetic oxide layer 11 has been coated. Such media is initially formed in a wide web, for example, 24 to 48 inches wide. It is then slit into one-half-inch-wide strips. This operation leaves the edge 13 somewhat dirty. In order to clean edge 13, the tape is passed over a cylindrical center body 15 with built-in edge scraper 16. During this operation, tape edge 13 is guided by fixed-position ceramic guide 18, and edge 14 is guided by movable guide 19 (see arrow 20).

Tape Edge Cleaning

The edge surfaces of magnetic recording tape are cleaned by subjecting the edges to the brushing action of edge guides, while at the same time scraping the polyester surface adjacent the edges, and then removing the scraped-off debris by use of a vacuum source. Tape 10 is about one-half inch wide, and is made up of a flexible substrate 12 on which a magnetic oxide layer 11 has been coated. Such media is initially formed in a wide web, for example, 24 to 48 inches wide. It is then slit into one-half-inch-wide strips. This operation leaves the edge 13 somewhat dirty. In order to clean edge 13, the tape is passed over a cylindrical center body 15 with built-in edge scraper 16. During this operation, tape edge 13 is guided by fixed-position ceramic guide 18, and edge 14 is guided by movable guide 19 (see arrow 20). Guide 19 is force biased toward edge 14.

(Image Omitted)

Guides 18 and 19 operate to brush tape edges 13 and 14, forcing the debris, etc. on the edges down into the cutting surfaces of scraper 16 and into the influence of a vacuum exhaust relative edge l4. Body 15 is hollow, and vacuum is applied to its internal cavity, to carry away debris.
