Abstract

In Fig. 1 a tape loop is shown positioned in a vacuum column 12. An air jet 14 is provided on one wall of the vacuum column that faces the loop of the tape. By directing a stream of air from the air jet onto the tape loop, the tape loop will be dimpled as shown in Fig. 2. As a result of the dimple, the tape loop will shift laterally. In this way it is possible to steer the tape loop in the vacuum column by use of the air jet 14.

Steering a Tape Loop

In Fig. 1 a tape loop is shown positioned in a vacuum column 12. An air jet 14 is provided on one wall of the vacuum column that faces the loop of the tape. By directing a stream of air from the air jet onto the tape loop, the tape loop will be dimpled as shown in Fig. 2. As a result of the dimple, the tape loop will shift laterally. In this way it is possible to steer the tape loop in the vacuum column by use of the air jet 14.

One use of the jet steering is to guide the end of the tape loop relative to a read/write head 16 which is placed at the end of the tape loop The air jet 14 is then used to index various tracks of the tape loop relative to the read/write head
16.
