Like a CD-R, a CD-RW has hardcoded speed specifications which limit recording speeds to fairly restrictive ranges. Unlike a CD-R, a CD-RW has a minimum writing speed under which the discs cannot be recorded, based on the phase change material's heating and cooling time constants and the required laser energy levels. Despite this, some ...
A compressed audio optical disc, MP3 CD, or MP3 CD-ROM or MP3 DVD is an optical disc (usually a CD-R, CD-RW, DVD-R or DVD-RW) that contains digital audio in the MP3 file format. Discs are written in the "Yellow Book" standard data format (used for CD-ROMs and DVD-ROMs), as opposed to the Red Book standard audio format (used for CD-DA audio CDs).
Those 74 minutes come from the maximum playtime that the Red Book (audio CD standard) specifies for a digital audio CD (CD-DA); although now, most recordable CDs can hold 80 minutes worth of data. The DVD and Blu-ray discs hold a higher capacity of data, so reading or writing those discs in the same 74-minute time-frame requires a higher data ...
CD-DA (Digital Audio) – originally published by Philips and Sony in 1981, [1] it was later standardized as IEC 60908:1987 [2] and later IEC 60908:1999. [3] CD-Text – a 1996 extension to CD-DA; CD-MIDI – part of the original Red Book standard; CD+G (plus Graphics) – an extension of the Red Book specifications used mainly for karaoke
An optical disc is designed to support one of three recording types: read-only (such as CD and CD-ROM), recordable (write-once, like CD-R), or re-recordable (rewritable, like CD-RW). Write-once optical discs commonly have an organic dye (may also be a ( phthalocyanine ) azo dye , mainly used by Verbatim , or an oxonol dye, used by Fujifilm [ 4 ...
In optical storage, three types of storage are usually recognized, and given customary abbreviations: read-only ("ROM"), Write once ("R") and read/writable ("RW", or for Blu-ray, "E" for "erasable"). Examples: CD-ROM represents the CD format, in its pre-recorded "read only" use; DVD+R represents a DVD "+" disc which can be written once only

If the data density is the same everywhere on the disc, as is the case with CD and DVD and Blu-ray discs, the linear velocity directly correlates with the transfer rate (read speed or write speed), meaning an increase in linear velocity also increases the amount of data read from the disc in the same time, regardless of whether the laser is ...
