Have any of you heard of the Thermal Magnetic Duplication (TMD) system? It was one of two well-known systems that were used for high speed VHS duplication, alongside Sony's Sprinter system.

Here's a list of duplication companies that used Otari TMD for their high speed work (there's more, but the following examples are ones that I saw on their websites via the WayBack Machine, or old newspaper and magazine articles all of which explicitly mention them using the Otari TMD system):

* 3M Co. (St. Paul, MN)
* Cassette Productions (The Duplication Group) (Salt Lake City, UT)
* Centercom Inc.
* Future Duplicators
* Mirror Image Duplication Services
* New Age Video (South Plainfield, NJ)
* Precision Tapes Inc. (Precision Powerhouse) (Minneapolis, MN)
* Premiere Video (Livonia, MI)
* Producers Color Service Video Cassette Division
* Rank Video Services America (Northbrook, IL)
* Resolution (Burlington, VT)
* Video Duplication Services, Inc.
* The Video-Matic Group (Salt Lake City, UT) (According to their website, they had five Sprinters and seven TMDs)
* VTR Video (Toronto, CA)
* West Coast Video Duplicating (MediaCopy)

Here's how the TMD system worked, according to the T-710 page on Otari's website (this was divided into three steps):

1. Mirror master tape production: Video signals played back with an 1" master VTR machine are recorded by a mirror master recorder (MMR. Otari R-750) as a mirror image of an original master tape on 1/2" metal-particle master tape.
2. Tape duplication: The mirror master tape is threaded on the high speed duplicator (Otari T-700, T-700II, T-700III or T-710) and made in an endless loop. The master and slave tapes are brought into contact using high pressure air at the print wheel, a precision air bearing with a mirror finished surface and an air cap, where the slave tape is rapidly heated by the laser light up to more than 130 deg C, and then immediately allowing the tape to cool while still in contact with the master to transfer the mirror image of the master tape to the slave tape. The latest T-710 can copy a 2-hour long movie program in about 24 seconds (NTSC-SP mode).
3. Tape loading: The printed slave tape is loaded into empty cassettes (V-0) by using 1/2" video tape loaders (Otari T-320II, VL-352). Loading is done automatically by detecting cue signals recorded at the beginning of the program. A T-120 cassette can be completed in about 20 seconds (with VL-352).

Precision Tapes also mentioned something on their website about the mirror master containing specific sections of 'black' video at the beginning and end of the tape, as well as what they called a 'Q-tone', both of which were mentioned as being used in the cassette loading process.

Have any of you heard of the Sony Sprinter system? It was one of two well-known systems that were used for high speed VHS duplication, alongside Otari's TMD system.

Here's a list of duplication companies that used Sprinters for their high speed work (there's more, but the following examples are ones that I saw on their websites via the WayBack Machine, or old newspaper and magazine articles all of which explicitly mention them using the Sony Sprinter system):

* Action Duplication (Conshohocken, PA)
* Allied Digital Technologies Corp.
* Arizona Media Duplication (Phoenix, AZ)
* Audio-Video-Color Corp.
* Color Film Corporation
* Copyrite Technologies
* Downeast Duplicating (Biddeford, ME)
* International Cassette Corp. (Greenville, TX)
* Mardee (South Plainfield, NJ)
* Paragon Media
* Precise Media Services, Inc.
* Premiere America
* Technicolor
* VideoLab Cassette, Inc. (New Brunswick, NJ)
* The Video-Matic Group (Salt Lake City, UT) (According to their website, they had five Sprinters and seven TMDs)
* VU Media Duplication (Denver, CO)
* WRS Motion Picture & Video Laboratory

Here's how the Sony Sprinter system worked, according to Paragon Media's website:

The Sony Sprinter System duplicates programs from a specially prepared "mirror mother master" (MMM). The MMM is recorded from a client's master onto a special VTR. Next, the MMM and the copy tape go through a magnetic field on the Sprinter, combined with a drive tape and the signal is transferred magnetically from the MMM to the copy tape. When completed, the copy tape is loaded into the videocassette. During the mastering process a cue tone is placed on the MMM. The cue tone signals the loader that the program is completed so it will do an exit splice.
