Of Implantation in Feurio!: | We have a sample of this writer available.
We have tested the writer in detail and have optimized the Feurio! driver. Nevertheless
we can not absolutely recommend this writer - see remarks. |
Footnotes:
| 1) | Hinweis zur Aufzeichnungs-Geschwindigkeit:
Der Writer ist ein "Zone ZLV-Writer", d.h. die volle Geschwindigkeit wird -
wie von vielen CD-ROMs bereits bekannt - nicht über das gesamte Medium erreicht.
Der Writer teil des Medium in mehrere Zonen ein. Jede Zone wird mit einer konstanten
Geschwindigkeit beschrieben (z.B. Zone 1: 16x, Zone 2: 20x, Zone 3: 24x).
Hierduch ergibt sich eine geringere tatsächliche Aufzeichnungsgeschwindigkeit
als die angegebene Geschwindigkeit. | | 2) | On
some CD-Writers the actually usable buffer memory differs from the size of present
buffer memory. In this case first the actually usable buffer size and then the
size of present buffer memory (taking e.g. from the technical specifications)
is shown.
This is caused by the recorder requiring a part of memory for internal purposes
or the number of maximum storable sectors is limited.
PRESUMPTION: Another possible explanation would be: Due to the error correction
information and other coding a sector occupies much more space (i.e. not 2048/2352
bytes per sector but about 4000 bytes) on the CD than in memory. If the information
would be converterd to CD format BEFORE storing them in the buffer, they would
correspondingly require more space in the recorder´s buffer memory. This
reduces the actually usable buffer size.
Example: Buffer memory = 2048 kb.
Size coded sector: 4194 bytes -> 2048*1024/4194 = 500 sectors can be stored
in the buffer. But in audio format these 500 sectors only represents 1148 kb
(500*2352/1024), so the buffer really stores only 1148 kb audio information,
although its physical size is 2048 kb.
