PINK FLOYD CD DISCOGRAPHY
Notes on CD discography
by Hans Gerlitz
CD DISCOGRAPHY
This discography includes the official releases of Pink
Floyd albums and albums from the band members,
singles, promotional and related issues on CDs.
Counterfeits, pirates and bootlegs are not included.
The discography is divided into three parts.
Basic Discography: Here you will find the listings of
all albums, singles and promos and general
information about every album, including track listing,
duration, release date and album credits. Even
albums that were only released as vinyl are listed
here. CDRs are not included.
The Main Part of the discography contains all known
editions of albums, singles, promotional issues and
compilations subdivided into country of appearance.
Every edition is accompanied by pictures of front- and
back cover as well as the CD. Pink Floyd albums are
listed separately from solo albums. European editions
are summarized, Asian countries are listed
separately, but clustered in one chapter.
The Appendix and Overviews covers miscellaneous
compilations. In Appendix you will find editions which
are not listed in the main part, such as band
member´s guest appearances, CDR issues, radio
shows etc. Overviews list the editions of special
interest like MFSL CDs or mini LP replicas which are
gathered together in one chapter, and with additional
pictures of the content. The Overviews chapters are a
repetition of already listed items in the main part of
this discography.
The sequence of this discography does not always accord
to the actual sequence of the editions. Some editions were
released almost simultaneously, for others the necessary
information to date the releases are missing.
Every chapter lists the albums in chronological order
according to the year of the original album releases.
As a matter of principle the original (not remastered)
editions are listed first, followed by the remastered editions
from the nineties. Particular first editions are put out as
such.
Chapters covering the solo works first register Syd Barrett
and then David Gilmour, Nick Mason, Roger Waters and
Richard Wright. It also applies here: The editions within the
artist's work are listed chronologically according to the year
of the original album releases.
In the Appendix ‘Guest Appearances’ you will find a sorting
of interpreters prior to the chronological sorting.
The pages of the discography are not paginated. The
discography is made for double-sided printing.
The discography is a reference guide, not a book on the
artwork of Pink Floyd. The photos of the artworks are used
solely for the purposes of distinguishing the differences
between the releases.
CD Format
The format of an audio CD (Compact Disc
Digital Audio) is described in a so called Red
Book produced in 1980 by the format creators
Sony and Philips. The format is a two-channel
16-bit PCM encoding at a 44,1 kHz sampling rate. The
selection of the sample rate was primarily based on the
need to reproduce the audible frequency range of 20Hz -
20kHz. The main parameters of the CD are as follows:
- Disc diameter 120 mm
- Disc thickness: 1,2 mm
- Centre spindle hole diameter: 15 mm
- Weight: 16 grams
- Scanning velocity: 1,2–1,4 m/s (constant)
- Playing time: 80 minutes
The first Compact Disc for commercial release (not a Pink
Floyd album) rolled off the assembly line on August 17,
1982, at a Philips factory in Langenhagen, near Hannover,
Germany.
CD Manufacturing
A CD is made from a disc of almost pure polycarbonate
plastic. A thin layer of aluminum or gold is applied to the
surface to make it reflective, and is protected by a film of
lacquer.
The clear plastic part of the disc is produced using a
hydraulic press. After the metallic layer is applied to the
clear substrate, the disc goes under a UV light for drying.
To press the CD, first a positive glass master is cut using a
high-power laser. After testing, it is used to make a die by
pressing it against a metal disc. The die then becomes a
negative image. In next step the die goes into the press
and the image is pressed onto the blank CD, leaving a final
positive image on the disc. A small circle of lacquer is then
applied as a ring around the centre of the disc, and a fast
spin spreads it evenly over the surface. The disc can then
be printed and packed.
CD data is stored as a series of tiny indentations known
as ‘pits’, encoded in a tightly packed spiral track moulded
into the disc. The areas between pits are known as ‘lands’.
Each pit is approximately 100 nm deep by 500 nm wide,
and varies from 850 nm to 3.5 µm in length.
The recording technology is identified mostly on the back
cover or on the CD by a three-letter code:
AAD: analogue tape recorder used during session
recording and subsequent mixing and/or editing,
digital recorder used during mastering (transcription).
ADD: analogue tape recorder used during session
recording, digital recorder used during subsequent
mixing and/or editing and during mastering
(transcription).
DDD: digital recorder used during session recording,
mixing and/or editing and mastering (transcription).
Matrix Number and SID Code
Like the catalogue number and the barcode (EAN, UPC
and IAN code), the matrix number is an additional
information which can be found on the CD. The matrix
number is engraved characters located around the inner
circle of a CD. These characters are used by the factories
at the stages of pressing records. Several CDs
manufactured in the same series usually have exactly the
same matrix numbers.
Some record collectors have extended the term “matrix
numbers” to apply to the complete alphanumeric codes
engraved around the centre of the CD. These codes
contain not only the matrix-number but also some
Information, like for example the Code 39 (same as the
usual barcode) as well as the so called SID Code (Source
Identification Code).
