This control track consisted of a clear line on a black background that varied in width.

Audio and control tracks are applied to the tape.

These numbers advance up or down based on the machine counting a tape's control track pulses.

The control track consisted of varying tones which corresponded to different volume levels.

Unlike preceding systems, 8mm did not use a control track on the tape to facilitate the head following the diagonal tracks.

An idler wheel, mounted at the rear of the vehicle, was used to control track tension.

A discontinuous control track was (and still is) especially problematic for analog videotape editing.

Trapped key interlocks were used in the 1890s, in the French railway system to control track switching operations.

Control track problems cannot be "repaired".

Every portion of controlled track belongs to a block, as blocks are laid out back-to-back along the entire length of the rail line.

Video head cleaner can used to clean video or audio or erase or control track heads.

The control track encodes a series of pulses, each pulse corresponding to the beginning of each frame.

The I.C.C. said it had made its decision partly because the rail carrier would control tracks that cross several state lines.

Eight distinct clubs combined in order to provide a more cost-effective method of controlling track rental fees and a more consistent competition field size.

Many incorrectly assumed that CTL timecode was nothing more than a control track pulse signal.

A control track is a track that runs along an outside edge of a standard analog videotape (including VHS).

The units had two audio tracks recorded on the top edge of the tape, with a control track recorded on the tape's bottom edge.

The procedure for entering LZB controlled track is repeated when a train transitions from one controlled section to another.

For this reason, many video professionals would "pre-stripe" every analog videotape to be used in the field or studio beforehand to help ensure good control track throughout.

New features such as note auditioning, transparent control track, toggling between playback and rendering, and expression control were implemented.

CTL timecode (Control track)

Both the loudspeaker switching and the gain of the variable-gain amplifier were under the control of a control track recorded on the Vitasound print.

The crew then developed the simpler Mark VI setup that consisted of three stage speakers, three program tracks and a three-tone control track.

Though either type of "loss" can pose similar problems, and both issues are sometimes directly related, control track and timecode are two different things (see timecode).

In DTC, controlled tracks and sidings (those requiring authority from the train dispatcher to occupy) are divided into pre-specified blocks.
