Audio Home Recording Act

The Audio Home Recording Act ( AHRA ) is a 1992 amendment to the United States copyright law that is tailored to DAT technology; it prohibits the manufacture, import and distribution of digital audio recording devices that do not have an SCMS or comparable system, and devices whose primary purpose is to circumvent, remove or deactivate such copy protection mechanisms.

The AHRA established a flat-rate remuneration system for digital audio recording devices and blank media in the USA ; one of the earliest examples of a lex digitalis .
