I added a Track Configuration page to the resources hierarchy in the sidebar at the right. This points to other resources on the web to provide further insight into the various analog audio track configurations. There is also a brief note there about the variation in the two-track, half-inch format. These differences are minor, but they could be a source of some problems under some extraordinary circumstances.
This page was updated 2012-01-05 to provide track widths on higher-density audio multi-track formats.
A link to the Studer track dimensions page was added 2012-01-06.
