Abstract
A helical scanning rotating head magnetic tape transport is provided for use with cassettes, and is arranged with vacuum means to pull a loop of tape from the cassette and helically around the rotating head scanning drum to a capstan and retracted pinch roller. The pinch roller is then automatically inserted into the bight of the loop, together with an element between the loop shanks to keep them apart during operation, and the vacuum means is then inactivated.
Claims25
In a rotary head type magnetic recording and/or reproducing apparatus having a cylindrical guide drum within which the rotary head is rotated, the combination comprising:
- means for mounting a tape cassette in the apparatus;
- a housing and differential air pressure means therefor for communicating with the mounted cassette and encompassing at least a portion of the guide drum to pull an elongated loop of tape from the cassette with a portion of the loop wrapped helically around the guide drum in the region of the rotary head;
- and
- means operable at a predetermined length of the loop of tape to separate the opposite shanks of the loop.
