Koch

KOCH is a nickname used by Austrian company [l=Koch Digitaldisc GmbH], which ran a CD manufacturing plant in Elbigenalp from 1985-1998. KOCH Digitaldisc merged with [l=Dureco] in 1998, after which the manufacturing plant continued operations under the name [l=kdg]. KOCH may be named in the disc matrix, or it may be identified based on the NNN.NNN.NNN.NNN.N and SID codes described in the following sections.

[b]Matrix numbers[/b]:
CDs manufactured by KOCH feature a matrix number in the format NNN.NNN.NNN.NNN.N. The first 6 digits, NNN.NNN, appear to be a sequential numbering scheme assigned by KOCH, which can be entered as the catalogue number for KOCH. The following 7 digits are often related to the release catalogue number, and should not be entered as part of KOCH's catalogue number.

Example:
[r17052828]
Catalogue#: [i]377.0029.2[/i].41
Matrix: [b]038.597[/b].[i]377.0029.2[/i]
LCCN entry: Pressed By – KOCH – [b]038.597[/b]

Example:
[r28106101]
Catalogue#: ENJ-[i]9301 2[/i]
Matrix: [b]812.829[/b].00[i]9.301.2[/i] ['mastered by KOCH' logo]
LCCN entry: Glass Mastered At – KOCH – [b]812.829[/b]

When the matrix number is in the form 000.000.NNN.NNN.N, no part of it should be entered as the catalogue number for KOCH.

[b]Preferred LCCN role(s)[/b]:
· Glass Mastered At - when the 'mastered by KOCH' logo is present in the matrix, or with mastering SID code IFPI L17*
· Pressed By - KOCH named in the matrix with no specific role given (with or without mould SID code), or with mould SID code 30**
· Made By - when the text 'MADE BY KOCH' is present in the matrix

[b]Glass masters[/b]:
Glass masters may originate from other manufacturers, probably before KOCH installed its own in-house mastering equipment. When 'CDMxx' is present in the matrix, please add Glass Mastered At – [l=CDM (10)] (see that label profile for more info) and credit KOCH with Pressed By or Made By as instructed above.
