Trading name for EMI Records Ltd.

This can be used for "Pressed By" on records and "Duplicated By" on cassettes manufactured between July 1973 and 2000 by that company.

Do not confuse with the record company E.M.I. Records, often followed by "(The Gramophone Co. Ltd.)".
For releases showing the "EMI" logo, see EMI.

EMI Records manufactured records at their record factories in Hayes, Middlesex. Originally, the plant was located on Blyth Road but moved to new premises at Uxbridge Road by July 1972. The 160,000 sq. ft. pressing plant consisted of a pressroom with 112 vinyl presses plus room for 28 more when needed, the sleeve store and sleeving area, as well as a tape duplication plant. The plant is famous for using the unique EMI 1400 presses, which were custom-built in-house and as such are the only presses of their kind in the world.

The plant previously operated as Portalspace Records Limited.

Records pressed by EMI Records always feature a runout machine-stamp unique to the EMI 1400 press, with a unique typography and a wide spaced typeface (see images for example).

For the pressing of EMI labels, the plant used the 9 and 3 o'clock locations for mother and stamper identity respectively (oriented to the matrix). For stampers the company used the 10-digit code "GRAMOPHLTD"; G=1 R=2 A=3 M=4 O=5 P=6 H=7 L=8 T=9 D=0. This was given up by 1981.

EMI Records was the first UK pressing plant to press DMM, starting in early/mid 1984.

Contract pressings:
The plant also undertook contract pressings for other companies from the late 1960s until 1999. Clients included Island Records (until 1974). Additionally, between 1988 (when the Polygram UK plant was closed) and 1992 (Polygram switched to other manufacturers), EMI also pressed for PolyGram UK.
The contract pressings never credit EMI Records directly.

Big hole/jukebox records:
EMI Records did not press 7” records with big holes apart from some specific items in the late 1980s and 1990s. Up until November 1966, EMI had pressed both solid centre 7” records and push-out centre 7” records with the latter being the most common, however, in that month the decision was made to only press 7” records with solid centres thereafter, apart from a small number of push-out centre singles for “special purposes”. One of these “special purposes” was export, and another was for use in jukeboxes. Later in the 1970s they seem to have reversed this and push out centres became common again but there is no evidence of big hole 45s with paper labels and EMI staff stated they had no presses that could do this.

In the last half of the 1980s, EMI introduced injection moulded 7” records and with the downturn in vinyl sales, jukeboxes became more important and some 7” injection moulded 45s were made with big holes. These are the only big hole 45s manufactured by EMI and any others with paper labels are post-manufactured “dinks”.

EMI pressings using lacquers from non-EMI studios:
The letter U was added at the stage of making the 'father'. It indicates that the lacquers were cut by an external (non-EMI) mastering studio.
The characteristic runout pattern is: -xU-m-n (e.g. -1U-1-7). A record with the following in the runout "LASH 19-A-1U-1-Q2" can be broken down as follows:
"LASH 19" is the catalogue number. "A" is the side identifier. "1U" is the cut number with U identifying the pressing as an external cut (i.e. that it was not cut at the EMI-owned Abbey Road Studios), "1-Q2" shows the mother and stamper numbers.
Often, the U is very faint and looks more like a J.

By 1993, the runout pattern did not contain the "U" cut or "Q" stamper indicators anymore but looks like -x-m-n (e.g. -1-1-7).
As before, a record with the following in the runout "B2B 12001 A-1-1-1" can be broken down as follows:
"B2B 12001" is the catalogue number. "A" is the side identifier. "1-1-1" indicates the cut-mother-stamper numbers respectively.
Leading zeros, e.g. -01-01-1 have also been used frequently (see this example).

A stamped "C" means that the mastering was done from an alternative source (not from the original master tape).
A stamped "D" stands for DMM, and indicates that the plant received a copper plate not a lacquer (since 1984).
Note: hybrid versions with mixes of -U -C and/or D are not necessarily variants and could potentially be different submissions - see here for separated examples. When in doubt, add as variant.

By April 1982 the runout matrix was combined at 6 o'clock.

The LP stamper ring diameter is 33 mm.
