Treatment criteria:

This protective sleeve is for the storage of analog audio discs of the 78 rpm, 45 rpm, or 33 1/3 rpm (LP) types.

The sleeve is made from Tyvek due to its silky, low-friction surface, which minimizes wear of the disc when it is removed from and placed into the sleeve. The sleeve also protects the disc from wear that would result from being stored in contact with other discs. However, it should be noted that it does not protect breakable discs against breakage. If this is a concern, additional storage measures need to be taken to address this.

Tools and materials used in this treatment


ruler or straight edge
bone folder


double-sided tape

Using the Manual

To facilitate convenient navigation and use, the procedural parts of this manual are presented in slide show form. As you can see above, clicking on the image shown on each treatment's front page begins the slide show.

Here are the navigational options within each slide. To view this information in illustrated form see the map image below.

Each slide offers the following capabilities:

* Thumbnail images of the entire treatment procedure are in a vertical column to the left. The progression is downward, beginning at the top and ending at the bottom. By clicking on any of these images, you can go to that point in the procedure.

* Clicking on any page's main image opens a larger version of the image in a separate window.

* Button links are provided to return to this page, to go to the next and previous slides in the series, and to go to the complete table of contents for the entire manual.

* The text is dotted with links to tools, materials, glossary terms, and other treatments. Linked text is gray in color and turns red when the pointer encounters it.
