Can A Cd Hold 90 Minutes Of Audio? Exploring Cd Capacity

The capacity of a standard CD, which typically has a diameter of 120 millimeters (4.7 inches), is primarily determined by the format of the content it stores. In the context of audio, these CDs can hold approximately 74 minutes of uncompressed stereo digital audio. However, for data storage purposes, they can accommodate about 650 MiB (megabytes) of data. To maximize the storage capacity, it’s possible to extend the CD’s duration to around 80 minutes or increase its data capacity to approximately 700 MiB. This extension is achieved by arranging data more efficiently on the same-sized disc, allowing users to make the most of their CD storage capabilities.

Is it possible for a CD to play more than 80 minutes of audio content? Typically, audio CDs purchased in stores are limited to a maximum playback time of approximately 80 minutes due to the physical storage capacity of the disc. However, if you decide to convert an album from a standard CD (known as CDDA) into digital formats like MP3 or AAC, it’s important to note that the resulting file will occupy less than 700 megabytes of storage space on your computer. This conversion process employs a method called lossy compression, which involves the removal of some data to reduce file size while maintaining acceptable audio quality. This digital conversion allows you to store and listen to music beyond the 80-minute limitation of traditional CDs. (Note: The information is current as of September 6, 2017.)
