In the recording industry, a cut-out refers to a deeply discounted or remaindered copy of an LP, 45 RPM single, cassette tape, compact disc or other item.
On CDs (a practice that continues today), a section of varying size is taken out of the spine of the jewel case and its paper track listing.
[1] Except for the physical damage to the liner notes and/or outer case, the actual disc (LP or CD) is generally unharmed by the cut-out process, and sounds exactly the same as the originally sold recording.
Besides the use by means of a discounted item, the cut-out method is also commonly used by record companies to mark copies that were sent out for promotional use to third parties like radio stations and DJs.
Cut-out (Chinese: 打口; pinyin: dǎkǒu) cassettes and CDs played an important role in the development of rock music in China.
