The Dark Side of the Moon CD masterings
1) Mastering Number 1 – Sony (Japan) Mastering
Track Peak Levels: 39.9 / 43.3 / 70.1 / 55.2 / 72.3 / 44.5 / 53.9 / 54.6 / 61.2
The very first mastering of Dark Side of the Moon for compact disc. Believed to be done by Sony Records in Japan in the spring of 1983. This mastering was used to produce the very first copies of Dark Side of the Moon on CD, which were Japanese releases with the catalog number CP35-3017 and a black triangle on the label, and a matrix number that did not include a “TO.” These early Dark Side CDs were pressed by CBS / Sony Records at their CD manufacturing plant in Shizuoka Prefecture, Japan for EMI Records. EMI did not have a CD pressing plant in operation at the time, so they outsourced the manufacturing of the CDs to CBS / Sony (keep in mind that these early Sony pressings still say Toshiba/EMI on the labels).
It is believed that this mastering was made from a 15ips reel-to-reel tape copy of the master tape that had been sent to Japan to produce the Dark Side Of The Moon-EMI/Toshiba Records Pro-Use Series vinyl LP album, which was the last vinyl pressing of Dark Side in Japan.
Known releases of mastering #1:
Australia first issue - Harvest Records, 7 46001-2, CD made in Japan
Japan first issue - EMI Records, catalog number CP35-3017, first pressings by CBS/Sony, indicated by no “TO” in the matrix
U.K. first issue - Harvest Records, catalog number CDP 7 46001 2, black Harvest label, Made in Japan on label, matrix has CP35-3017 with no “TO”
U.S. issues:
First issue - Harvest Records, catalog number CDP 7 46001 2, black Harvest label, Made in Japan on label, CP35-3017 in the matrix

Third issue - Capitol Records, catalog number CDP 7 46001 2, silver label, Made in USA on label, TO J in the matrix*
Fourth issue - Capitol Records, catalog number CDP 7 46001 2, silver label, Made in USA on label, CP35-3017 TO J in the matrix*
* Note: It is interesting to note that the 2nd through 4th U.S. issues of Dark Side of the Moon were pressed by the Toshiba/EMI pressing plant in Japan (as indicated by the “TO” in the matrix). Yet these pressings use the 1st (Sony) mastering of the album. It is believed that the Toshiba/EMI plant in Japan began operations in late 1985/early 1986, and began pressing Dark Side with the Sony mastering until a new master by EMI (master #3 in this listing) was created in late 1986. Once EMI had made their own master (#3), all pressings of Dark Side used the EMI master.
2) Mastering Number 2 – Sony (U.S.) Mastering?
Track Peak Levels: 46.8 / 48.2 / 49.3 / 51.0 / 72.5 / 63.3 / 67.1 / 58.8 / 62.7
The very first compact disc manufacturing plant that was built in the U.S. was the Digital Audio Disc Corporation [Sony DADC] plant in Terre Haute, Indiana, which opened May 2, 1983, with commercial CD production at the plant starting in September 1984. Early copies of Dark Side of the Moon that were pressed at this plant had a unique mastering. This mastering may have been done by Sony DADC in the U.S. as this mastering is unique to these
U.S. pressing. This mastering was never issued outside the U.S.

On May 15, 1986, EMI Records opened its first CD manufacturing plant in the U.K. at its VHD facility in Greenbridge, Swindon, England. Prior to this facility opening, EMI Records had used outside companies to master their CDs for them. But with its own production facility in operation, a new mastering of Dark Side of the Moon was done. It is believed to have been done at the EMI facility in Swindon. This mastering was the very first "EMI" mastering of Dark Side of the Moon for compact disc, and is thus referred to as EMI revision 0.
One of the most common masterings of Dark Side of the Moon found on CD.

A revised mastering was done of Dark Side of the Moon by EMI Records in the late 1980s. Possibly done at by EMI at their Jacksonville U.S. plant or perhaps done by EMI Canada? Appears to be unique to North America. This new EMI mastering can be identified by a RE1 (indicating revision level 1) in the matrix.

Track Peak Levels: 29.3 / 34.1 / 39.2 / 40.3 / 41.5 / 56.3 / 49.2 / 57.8 / 52.9 / 60.0
In 1988, Mobile Fidelity Sound Lab, a high end audio company got permission to produce Dark Side of the Moon on compact disc, using the original master tape as the mastering source. It is believed that this was the first time that the original master tape was used as the mastering source.
In April 1988, MFSL released, under license from EMI/Harvest Records, the Dark Side of the Moon UlrtraDisc CD, which was based on a completely new mastering done by Mobile Fidelity. These UltaDisc CDs were pressed by Ultech in Japan for MFSL. In 1993, MFSL released an UltraDisc II version of the MFSL mastered Dark Side of the Moon CD. This UltraDisc II used the same mnastering as the UltraDisc. It was first manufactured by Zomax Optical in Plymouth, Minnesota, and then later by JVC in Japan.
Known releases of mastering #7:
MFSL UltraDisc, catalog number UDCD 517
MFSL UltraDisc II, catalog number UDCD 517
Mastering Number 8 – Columbia Records mastering for Shine On box set
Track Peak Levels: 35.0 / 69.5 / 69.9 / 77.7 / 75.8 / 94.2 / 70.4 / 91.2 / 75.5 / 83.2
In 1992, it was decided to include Dark Side of the Moon in the Shine on Box Set. This box set was a nine CD box set with a 112 page hardcover book on the history of the band. The box set was issued by Columbia Records in the U.S., and apparently Columbia Records did not use the EMI masterings of the EMI discs that were to be included in the box set, so they did masterings of their own.
This unique Dark Side of the Moon mastering is only found in the Shine On box set.
Known releases of mastering #8:
U.S. issue - Shine On box set, Columbia Records, catalog number CXK 53180-S1, released November 17, 1992

In 2003, for the 30th anniversary of the release of Dark Side of the Moon, it was decided to do a special 5.1 channel remix of the album for release on SACD by James Guthrie. This special release also included a stereo remix of the album. Since the EAC software does not read 5.1 SACD layers, the track level reading above are those of the standard stereo layer on the CD.

In 2002, EMI began manufacturing all its CDs for the European market, including all U.K. releases, at its plant in Uden, Netherlands. The new pressings are noted on the outside as E.U. (European Union) releases. And the latest release of Dark Side of the Moon produced in Uden has yet another mastering. This could possibly be EMI revision level four for those of you keeping count!

Over 35 years have passed since the release of Dark Side of the Moon, and 25 have gone by since it was first placed onto compact disc. As far as I can tell, there are eleven different CD masterings of the album. Most of these are out of print and can be found only from Collectible Shops.
It is interesting that if one were to purchase Dark Side of the Moon today, you can still buy the SACD issue, plus a standard stereo issue.
If you buy the latest issue in the United States, you will be buying mastering number 9, the twentieth anniversary mastering of the album in a standard jewel case, which is now being pressed by Cinram International in Richmond, Indiana.
If you purchase the latest issue in Europe, you will be buying mastering number 10.
If you purchase the latest issue in Japan, you will be buying mastering number 9.
