This is the dominant color of the case. Many CD jewel cases consist of plastic and a tray that can be one of many colors. Therefore, a case with a black tray would be noted here as being a black case.STYLE
Media cases can have several different styles for each type. Below are some of our most common styles.CAPACITY
Standard: These are cases that are close in dimensions to what is considered to be the industry standard. Most of the time standard size cases hold one or two discs.
CD Cases are about 5.6" x 4.9" x 0.4" (142mm x 125mm x 10mm)
DVD Cases are about 5.3" x 7.5" x 0.6" (135mm x 190mm x 14mm).
Blu-Ray Cases are about 5.3" x 6.7" x 0.5" (135mm x 170mm x 12mm).
Multi Standard: These are similar in width and height to the standard type. However, the thickness can vary significantly, but are always thicker than the standards listed above. We classify a "multi" case as one designed to hold 3 or more discs.
Slim: Typically, these are similar in both width and height to the standards. However, the thickness is less than the standard allowing the user to save space. The main drawback is that there is less room for labeling on the spine and some slim CD cases may lack a rear trayliner that pops out for easy access the the spine. Furthermore, some DVD or Blu-Ray cases may not contain inside clips that hold literature and artwork.
Multi Slim: As with the other styles, these are usually similar on both height and width. We classify a case as this when it is designed to hold 3 or more discs with a thickness that is, typically, thinner than normal. Some of these cases can come as thin or thinner than the standards. Sometimes, in order to achieve this size some features may be left out or the inside design may be different than normal.
This indicates the number of discs the case is designed to hold.TRAY
This is the plastic part of the case that holds the actual optical media. This field is use mostly to describe our tin cd/dvd case products. These trays can come in various colors like light blue, clear and black. They also hold the discs in different ways:WINDOW
Center Snap Hold refers to when the optical media is secured by snapping it into the hole in the center. This is the most common way to hold a disc. Some have specialty designs including the M-Lock Hub. This is a premium hub designed to hold a disc in place more securely than any other on the market today. Further, this is accomplished while allowing the user to easily insert and remove the media.
Center Spine Hold are trays that hold the disc on a spine (a small version of what you might find on a spindle). Longer spines have higher capacities. Several tin styles feature this. However, we advise against storing more than one disc into any of the Rounded D-Shape shapes. There is limited space between the disc and case edges making it potentially difficult to remove multiple discs.
Outer Edge Hold are found primarily in the rounded tin shapes. The capacity of these is one disc. The media is held in place by snapping it into the outer edges of the plastic. Since this is a method unfamiliar to many people, it may take a little bit of getting used to.
Several tin cd/dvd case models have a clear round plastic window that allows all or part of the disc to show through. If the model you are viewing includes a window, the diameter will be listed in this space.DIMENSIONS
This is the width, height and thickness of the case. Most of the time, we list dimensions in that order (W x H x T). Please note that dimensions on our site are sometimes listed in mm (millimeters).FEATURES
Product dimensions stated on this site are accurate to within 1.5mm or 1/16 inch.
To convert millimeters (mm) to inches, take the number of mm and divide by 25.4. For example, if the height of a case is 190mm you would divide 190 by 25.4 and get 7.480314. Therefore, this case is just shy of 7 1/2 inches high.
Here are a few common conversions:
Below is some other terminology you may find to describe our cases:
Inside Clips or Tabs: Many cases have clips or tabs designed to hold paperwork inside the case. Typically, these are located on the left side of the open case.
Clear Plastic Wrap: This is found on most DVD and Blu-Ray cases and some CD cases (usually those made of a poly material). The wrap will usually cove the front, back and spine and allow a label to slide under it.
Inside Tray: This is found in many multi cases. It is a tray that, when the case is open, can flip back and forth. The tray can have hubs to hold discs on one or both sides. It is possible (depending on the thickness of the case) to have many trays allowing for large capacity cases. Oftentimes, these trays can easily being removed by the user.
Overlap Style: Also known as "overlay" is another method to increase the capacity of a case. It works by having two hubs (one above the other) where normally one hub is found. One of the two hubs is deeper thereby minimizing contact between the 2 discs being housed in that area. This style is only found in DVD or Blu-Ray cases due to size constraints of most CD cases.
M-Lock Hub: This is a premium hub designed to hold a disc in place more securely than any other on the market today. Further, this is accomplished while allowing the user to easily insert and remove the media.
