NOA’s CD-Lector station is a 4/8 parallel single drive mass CD-ripping system designed to extract audio from CD into digital audio objects with perfect control over interpolation to deliver for optimal results even for heavily damaged items. The user is prompted for the right carrier to be inserted in the drive with automatic opening/closing of the corresponding drive in automatic mode. Alternatively, the carrier barcode can be used to fetch the corresponding metadata item to be digitised. In most cases digitisation of the carriers requires no hands on operation. CD-Lector includes algorithmic analysis as well as advanced metadata retrieval and supports four read modes:
Archive Mode reads all sectors up to 64 times and will only move on to read the next sector if it has an exact match between two read results.
Burst C2 Mode reads sectors once only and changes the read mode only on receipt of a C2 report from the CD–ROM drive, also flagging up the read mode change.
Alternate Mode is a response to the potentially long grab process in Archive Mode’s 16x - 64x setting. Users can specify a time/speed offset, after which the mode automatically changes to a slow Burst Mode, while flagging up the read mode change.
Burst Mode can be used for CDs, when no other method of grabbing will lead to a result. Burst Mode is a single pass mode with the highest speed (typically 28x) and no security, except for Algorithmic Scanning.
Why NO Jukebox?
Archivists usually invest in such machines because processing the work will take years and years. However, 100,000 CDs can be extracted with the NOA CD-Lector within less than a year, as the grabbing speed in NOA´s Archive Mode is around 10x speed. Several reasons make a jukebox a less desirable solution:
- CDs have to be loaded in the correct order, since EAN codes are generally not available
- any mistake in the loading process could put all the results out of kilter
- crosschecking of content to metadata takes at least 40 seconds extra per CD
- it involves an operator for about 1 hour’s “pre jukebox” and 3 hours’ „post jukebox grab“ work
