Do Memorex Ultra Speed CD-RW's Stink?

Postby craiger on Tue Sep 30, 2003 8:02 pm

Hi. My LG 48x24x48x CD-RW drive can read other CD-ROM's but they seem to have trouble reading Memorex Ultra Speed CD-RW's. The DVD-ROM can read them not my LG. I noticed some scratches on some of my Memorex CD-RW's. How deep does a scratch have to be to effect the CD-RW? Thanks, Craig.

Do Memorex Ultra Speed CD-RW's Stink

Does the pope go in the woods?

One of the worst media ever created (Infodisc), there's plently of threads and posts about them.

Memorex 10x CD-RWs (also Infodisc) are pretty bad as well.

Melody 24x CD-RWs are also made by Infodisc, and are at LEAST as bad as the Memorex ones... although from my own experiences compared with what I've read, and the scans I've seen posted, the Melody branded discs may even be WORSE quality then the Memorex! :evil:

Those Melody discs must be terrible; I've seen some awful results from the Memorex 24x discs!

I haven't had a single USEABLE burn yet, and that's using the Plextor Premium drive to burn them!

and when I say they aren't useable, I mean every single burn has many unreadable areas with significant data loss :evil:

To be honest, I'm surprised Memorex and Melody still sell this media. The quality is so poor that I would think that anyone who bought them would return them quickly and complain to the manufacturer or the seller.

My Memorex 12x CD-RW's (Infodisc) work fine. I don't think the quality is up to par with other disks, but they are readable, and for RW's, that's all that counts for me.

The Memorex 12x and 10x discs that I've used are readable, too, but the write quality on them is terrible. Here is the ATIP of one of the Memorex 12x CD-RWs:

Drive Type = CD-RW
Disc Type = HIGH SPEED CD-RW
Material = Phase Change
Lead In = 97:25:30
Lead Out = 79:59:73
Nominal Capacity = 702.83MB (79m 59s 73f/LBA:359848)
Manufacturer Maybe = Infodisc Technology Co., Ltd.
Smart-Burn Speed Limit = Wrt(10X),Rd(40X)

Here is a KProbe scan of this disc written at 10x in an LTR-52327S:

The recording quality of these discs is also very bad when written on a NEC 16x10x40x CD-RW drive (I forgot the model number as it isn't mine).


In contrast, here is a 12x Philips disc written at 12x in the same drive.

Drive Type = CD-RW
Disc Type = HIGH SPEED CD-RW
Material = Phase Change
Lead In = 97:26:65
Lead Out = 75:00:00
Nominal Capacity = 658.89MB (75m 00s 00f/LBA:337350)
Manufacturer Maybe = CMC Magnetics Corporation
Smart-Burn Speed Limit = Wrt(12X),Rd(40X)

Image

Interestingly, the Memorex RW has been written and erased far less times than the Philips one.

I tend to avoid Memorex CD-RW discs and DVD-RAM (when I had a RAM drive).
Their CD-R, 4X DVD+R and 4X DVD+RW media are fine however...
Burners only:
Pioneer DVR-115D
Pioneer DVR-111D
Plextor PX-716A TLA0304
Plextor PX-716A same TLA

LiteOn 52246S 52X CD-RW
LiteOn 52246S (another)
LiteOn 52327S 52X CD-RW
TDK 40X USB 2.0 CD-RW
TEAC CD-W540E 40X CD-RW

their CD-Rs are all over the place! depending of course on who they had manufacturer them that week. Honestly, Memorex has more manufacturers producing their media then any other brand. My major beef with Memorex is that their CD-R have this nasty tendancy of being anywhere from nearly top notch to bottom of the barrel, with little to no distinguishing between them (it either says made in Japan or made in Taiwan, other then that you're out of luck)

I see what you mean, Dolphinius_rex. I have some very good Memorex discs that are made by TY, but I otherwise have avoided Memorex for the reason you mentioned.
