MiniCD

From Biocrawler, the free encyclopedia.

MiniCDs are smaller form-factor CDs

Amongst the various formats are the

• CD single, an 80 mm disc. The format is mainly used for audio CD singles in certain regions (singles are sold on normal 120 mm CDs in many countries), much like the old vinyl single. An 80 mm disc can hold 21 minutes of music, or 180 MB of data. They are often refered to as Maxi CDs in some countries.
  • The low density version holds 18 minutes, or 155 MB.
  • An enhanced density version of the 80 mm disc holds 34 minutes, or 300 MB.
• Business card CD, a truncated 80 mm disc with a storage capacity of around 50 MB.
  • The long axis is 80 mm while the short axis is 60 mm
  • The disc may be rectangular with wings added on, to square off the rounded 80 mm disc.
    • The long edges is 80 mm, diagonal axis is 85 mm, and the short axis being 60 mm
• 60 mm disc, a round version of the business card, with the same capacity (50 MB)

When MiniCDs were first introduced in the United States, they were initially marketed as CD3, in reference to their approximate size in inches; larger CDs were called CD5, despite the fact that both CD specifications are defined solely in terms of metric units. These names failed to gain wide acceptance.
