Testeurs pour CD
Tester vos CD-R est une procedure necessaire pour toute application
professionnelle d archivage. En effet, les CD-R vieillissent
selon des criteres lies au couple Media / Graveur (CD-R vierges
/ burners), a la qualite de fabrication initiale des disques
et a l environnement ou exposition des CD-R apres gravure.
De plus, la lisibilite (playability) est liee a la qualite
et la geometrie des pits formes, et au respect du format encode.
Les differents parametres constitutifs de l echelle de qualite
globale du CD-R finalise se mesurent sous forme d'erreurs
numeriques (BLER E11, E12, E32, E21, E22, E32 et BURST) et
analogiques (I3, I11, ITOP, Reflectivite, Beta, Asymetrie,
jitter, bruit radial (radial noise), acceleration radiale,
erreur de tracking et de focus).
Nous distribuons exclusivement les testeurs de la societe
suedoise StageTech sur le marche Francais. Ces testeurs se
declinent en 2 gammes: EC2 et QA2.
Vous archivez sur CD-R, il est important de tester les CD
finis afin de controler la chaine de gravure, un controle
elementaire peut etre effectue par l analyse en temps reel
des erreurs numeriques (EC2), un controle
plus approfondi peut etre effectue par la mesure des signaux
analogiques (QA2)
Les testeurs que nous distribuons sont tous fournis avec
des pickup slectionnes et repondent a l'architecture de decodage
Sony / Philips (RED, YELLOW et ORANGE Book). Les logiciels
d'affichage VISION 1 et SPLIT Vision (jusqu'a 4 testeurs)
permettent un affichage graphique evolue et une classification
parametrable (i.e. norme AFNOR Z42-11).
Pourquoi s'equiper d'un testeur plutot que de confier a des
prestataires exterieurs ce travail : Controle in situ de la
securite des disques et possibilite d'auto controle par disque
de callibration fournit.
3 raisons principales pour un bon archivage numerique sur
CD-R :
- Mesures identiques a celles de l'industrie (disque de
reference Philips 5B)
- Reproductibilite des mesures d'un testeur a l'autre de
par la selection des pickups (test croises)
- Repetitivite des mesures sur le meme test

Definition of QA2 CD Analyzer
QA2 is a Quality Analyzer for small as well as major installations
providing full control over the manufacturing process of CD´s.
Different areas in the production chain from checking CD-R
masters for the Glass mastering to analysing replicas in the
production line is covered. The QA1 is the basic analyser
with the possibility to upgrade to other models in the QA
Series. Fully automated verification of Table of Contents,
PQ data and Error rates combined with digital audio playback
are some of the features.
The QA2 is the second generation Analyser in the QA Series.
With basic HF measurement and all the features from the earlier
model QA1, this is the most cost effective CD Analyser in
its category. Fully automated verification of Table of Contents,
PQ data and Error rates combined with HF measurements are
some of the features.
The QA Series Analysers are affordable, easy to use CD and
CD-R verifiers with applications in CD replication, CD-R duplication,
Glass-Mastering and Archiving.
QA2 as a CD Analyzer
CD's are checked against the CD Specifications. Parameters
include TOC and PQ information, Status bits, UPC/EAN and ISRC
data, full Error statistics and Basic HF parameters (QA2 only).
All CD formats tested, including: CD-Audio, CD-ROM, CD-ROM
XA, CD-I, Video-CD, Photo-CD, CD Extra, and any combination
of mixed mode, multisession and ready (hidden track) formats.
The self contained 3U mount unit houses a specially selected
optical chassi for maximum repeatability and accuracy. This
means that the user will always get the same result in the
same tester or in any other unit in the QA Series. Control
of the dedicated hardware is handled by an internal PC. Software
and format upgrades are easily accomplished via the built
in floppy drive.
QA2 Outputs and Parameters
Outputs are provided for printer, alarm, headphones, analog
and digital audio. Optional is Ethernet network connection.
Parameters for configuring the Display, File handling, Printing,
Auto functions, Warning and Failure Error levels and DDP file
generation can all be set using the accompanying Windows based
Setup software. Error statistics can be output to a printer,
to a network or to a diskette.
An optional Windows based Control & Display software,
VisionOne, is available for installation on a separate PC,
communicating over RS-232 and displaying graphs, tables and
TOC/ETOC info on a VGA-screen as well as providing high-resolution
print-outs. A more elaborate version, SplitVision, is giving
the possibility of split testing with up to 8 testers divided
in up to 4 different groups, each group handling a maximum
of 4 testers.
