That was then

In 1949, WTIC-AM, Hartford, CT, purchased three Magnecorder stationary tape recorders plus one portable unit. One of these can be seen in this photo in the rack on the left. Al Jackson, an engineer for the station at that time, is checking a transcription disk, which was also used extensively at that time. A microscope was used to ensure that the cut groove was at the proper depth and sufficiently separated from the adjacent cut. The audio console to the right set the level feeding the transcription recorder. In the foreground is a turntable typical of those used to play the transcription disks.


Do you remember?

Twenty-two years ago the Otari MTR-10 Series production recorders were available in four formats: 1/4" full-track, 1/4" two channel, 1/2" two channel and 1/2" four channel. Each version provided three-speed operation with individual equalization and bias, two master bias presets and controlled wind for library spooling. The units offered back timing, an on-board test oscillator, user-adjustable phase compensation and speed display in percentages or IPS. The recorders featured +/-20 percent varispeed and an optional 10-memory locator. The recorder's frequency response was 50Hz to 20kHz, +/-0.5dB and it offered a signal-to-noise ratio of 75dB.
