The time between echo repeats was adjusted by varying the tape speed.

Because of the low tape speed, the achievable bit rate was limited.

The recorded frequency range was dependent on the linear tape speed.

It is technically impossible because the mechanics of tape speed and image resolution don't work that way.

I rewound, switched the tape speed, and tried it again.

The formatting track made operation almost independent of tape speed, which was, in fact, quite variable.

The code itself, even if they record it and find the right tape speed, cannot be broken without a computer.

The tape speed is one of the things that finds out the playback time.

He set the tape speed on superlong play and looked around the room until he saw it.

This required the system to run at a high tape speed of 11.26 inches per second.
