Technics SL-1210MK2 turntable pitch control slider. A variable speed pitch control (or vari-speed) is a control on an audio device such as a turntable, tape recorder, or CD player that allows the operator to deviate from a standard speed (such as 33, 45 or even 78 rpm on a turntable), resulting in adjustments in pitch.

Sony developed DVCAM based on the DV consumer format. The DV format was designed for use with metal evaporated tape, which offers approximately 5 dB better carrier-to-noise figures than metal particle tape. Customers have requested VTRs that can play additional DV-based 6 mm formats such as the consumer DV LP and DVCPRO.
The control track is used to fine-tune the tape speed during playback, so that the high speed rotating heads remained exactly on their helical tracks rather than somewhere between two adjacent tracks (known as "tracking"). Since good tracking depends on precise distances between the rotating drum and the fixed control/audio head reading the ...
In the case of VHS, a linear control track at the tape's lower edge holds pulses that mark the beginning of every frame of video; these are used to fine-tune the tape speed during playback and to get the rotating heads exactly on their helical tracks rather than having them end up somewhere between two adjacent tracks. However, the exact ...
All DCC players and recorders are auto-reverse, so every player and recorder must have a way to position the heads for the A-side as well as the B-side of the tape. In stationary recorders, the mechanism switched sides by pivoting the head assembly 180 degrees (Philips used a modified version of an analog auto-reverse cassette deck during ...
Canon began developing a still video system as early as 1977 following a secret presentation from Texas Instruments (TI). Processing the image data from a CCD sensor into a digital file would have required a supercomputer at the time, so a strategic decision was made to use analog recording methods, and Canon recruited Sony and other manufacturers to create a standard format, resulting in the ...
