Yamaha 8424s SCSI CDR-W - Page 7

FAQ

Is Yamaha 8424s any good?
Yamaha 8424s seems to be the best Yamaha CDR-W ever tested..

When Yamaha going to support CD-Text?
The next generation after 8424x will support CD-TEXT. This new generation will be launch on Spring-Summer 2000.

Is there any possibility with firmware upgrade to include CD-Text on current Yamaha Models?
No, because for supporting CD-TEXT you need a Red Book LSI (Chipset) and firmware modification. Sony created CD-TEXT and they sales LSI chipset to other manufacturer. Yamaha built is own red Book LSI chipset. The next generation will have a new red Book LSI chipset with CD-TEXT and faster DAE (above 24X!!)

Why don't Yamaha CDR-W drives support read/write RAW?
When you use MMC-3 (ANSI Multimedia Command Set SCSI-3) standard is quite difficult to implement RAW read/write..That's why all newer CDR-W doesn't support it..

Why i should (or not) care about RAW read/write?
Read/write RAW is very useful to users..With the arrival of CloneCD users, which their CDR-W supports RAW read/write, can do <backups> of their protected CDs..

Is Yamaha plans any 12x CDR-W drive soon..
Yamaha Japan is developing for Q3 2000 a Ultra speed CD-R/RW drive. The pick up will be specially designed for High speed..

Hmm..How come other manufactures released 12x CDR-W before Yamaha?
Other manufactures used pick from Sanyo. Sanyo Pickup are generally boosted. The 8X Sanyo pick up series cannot write in 6X because originally they have a 4X structure. So they write in 1X 2X 4X and 8X (the 8X is a 4X boosted). It's the same for the 12X. The pick use a 8X technology and it's boosted to 12X.

It is much easier for some manufacturer to make fast drive but the reliability of the writing is not very good. Yamaha 8X technology it's the same for Sony and Philips because it's take time to create a real 8X pickup with a good pricing.

Why various programs like Feurio reports that Yamaha 8424s uses only 3.0 of 4.0mb buffer?
Like all Yamaha burners, the size of the useable buffer is less than the size of the total buffer.

From Feurio Support (Actually is for 4416x series but also fit..): The answer of the Yamaha support was: "The size of the dDRAM is 2 MB however the area for the host is 500 blocks. For instance, in case of Mode 1 data (2048 bytes per block) the buffer area for the host is 2048x500 byte. In case of audio-data (2352 bytes per block), the buffer area for the host is 2352x500 byte (1,176 MB)."

Any plans for 6x CDR-W?
Wait till Cebit 2000..

When we should expect to see DVD+RW (or possibly a DVD-R) from Yamaha?
Yamaha is working on DVDRW 4.7GB format but we expect this drive for 2001. HP and SONY said on Comdex they launch DVD+RW 4.7 on 2001. Everybody is delaying because the CD-R/RW is bigger market (objective: replace the floppy disk) and the DVD-FORUM haven't yet decided for a DVD RW standard. So, we have to wait...

How come 80min CDs are now officially supported by Yamaha?
80min CD-R are officially supported by the Orange book chapter II release 3.1. The CRW8424 have this specification. The 6416, 4416 and before support only the Orange book chapter II release 2.0 (support only 74min and 63min). That's why 80 min wasn't supported before by a lot of drive into past..

Hmm? My 4416,6416 can write 80min CDs...What you are talking about?
CRW4416 and 6416 support CD-R 80 minutes but unofficially because the Orange book ver3.1 chapter II wasn't available at this time. Yamaha is one of the leader of the Orange book forum and OSTA, so since CDR400, Yamaha was able to activate 80min unofficially.

The problem of the 80min is during a long time, the pressure of CD audio manufacturer and Game editor was very strong and they didn't want to see 80min CD-R on the market (remember TDK in 1996-97 was the first to have a CD-R 80min but under pressure they should increase the price to $20). Last Year Taiwan manufacturer like Ritek and Lead Data start to produce CD-R but to have a new market they start to produce cheap 80min without caring the pressure of CD audio manufacturer and Game editor. so now, the Orange book forum have to confirm the Orange book ver 3.1 chapter II, and some major manufacturer CD-R brand like Philips make 80min.
