New Aleph Location Codes for the Walter SMART Learning Commons collections

Walter LRC has become the Walter SMART Learning Commons! Please use the following location codes for Aleph item records:

SLC SMART Learning Commons
SLCC SMART Learning Commons (Closed Stacks – Ask at SLC Desk)
SLCD SMART Learning Commons (Desk Coll. – Ask at SLC Desk)

The WALT, SLC code should be sufficient for most materials (especially video). If you inadvertantly use the "old" code in the Aleph item record, the system will correct it to the new code.

Trivia: What's up with 007 coding for CD speed?

A recent discussion on the AUTOCAT list addressed the reason why the speed of an audio compact disc is 1.4 meters per second (007/03 f). Just in case you're curious, here's a good explanation of why this is the case:

"CDs and DVDs address this by using what is called Constant Linear Velocity (CLV) The surface moves past the read head at a constant rate. This means as the pickup head moves from the center toward the edge of the disc, the disc does not have to turn as fast since there is more ground to cover. It is akin to the old "whirly go round" at the park. The kid on the outside had to run fast, but the kid in the center barely had to move. The rate chosen was 1.4 meters per second. As the disc plays, there is more "landscape" to record on so the disc doesn't need to move as fast."

Know your shiny discs: Dual Disc

Here's another shiny disc format to know about: dual disc. Dual disc is a double-sided disc that has a DVD layer on one side, and a CD layer on the other side. The idea is that a Dual disc can include a full-length high-quality sound recording on its CD side, while it can contain video content relevant to the music on its DVD side.

Many DVD-Audio discs also contain both audio and video content, but unlike DVD-A, Dual discs don't require special equipment -- they are supposed to be playable in any DVD or CD player. Each side of a Dual disc is clearly marked DVD or CD. More information about Dual disc is available in this FAQ.

Some industry commentators have raised issues about the format. First, there is concern that Dual disc's CD side is not quite fully compatible with the "Red Book" standard that CDs are supposed to meet in order to guarantee their playability in every machine. Second, Dual discs may be too thick to work in slot-loading DVD/CD players -- like car stereos and some laptop drives. If a consumer tried to use a too-thick disc in a slot-loading system, the disc would likely become stuck, and the player/drive would have to be serviced. It is too early to know if these will be major issues for Dual disc.

Dual discs have only been widely available since October 2004 and haven't really taken off just yet, so there's a good chance that we won't see any for a while (if we ever do). But how would you catalog one, if by chance it turned up? You would follow the same basic principles used for Enhanced CDs, DVDs with both video and computer disc content, or DVD-As with audio and video. Here are some tentative guidelines:

How to tell the difference between a CD-ROM and a DVD

Sometimes it's hard to tell whether a disc is a CD-ROM or a DVD, especially when the publisher gives no indication. Here's one way to tell when you can't tell any other way:

  1. Put disc in your computer and wait for it to load up.

  2. Open Windows Explorer. Find your CD/DVD drive (usually the D: drive) under "My Computer."

  3. Right-click on the CD/DVD drive icon. A menu will pop up.

  4. Choose Properties from the menu. This will open a window with technical information about the disc in the drive.

  5. Check the size on the Properties window. If it's under 700 MB, it's probably a CD-ROM. If it's over 700MB, it's almost certainly a DVD (a DVD can hold up to 4 GB of data, while a CD can only hold up to 700 MB).
