If this option is checked, K3b enables Burnfree (or Just Link). This is a feature of the CD writer which avoids buffer underruns. Without burnfree, if the writer cannot get any more data a buffer underrun would occur, since the writer needs a constant stream of data to write the CD. With burnfree the writer can mark the current position of the laser and get back to it when the buffer is filled again; but, since this means having little data gaps on the CD, it is highly recommended to always choose an appropriate writing speed to prevent the usage of burnfree, especially for audio CDs (in the worst case one would hear the gap). Burnfree was formerly known as Burnproof, but has since been renamed when it became part of the MMC standard.
Aukera hau aktibatzen bada, K3b- k Burnfree (edo Just Link) gaituko du. Eginbide honek CD grabagailuak bufferra hustutzea saihesten du. Burnfree gabe, grabagailuakezin duenean datu gehiago lortu bufferra hutsik egotea gerta daiteke, baina grabagailuak datuen korronte jarrai bat behar du CDa grabatzeko. Burnfree- rekin grabagailuak laserraren uneko posizioa markatu dezake eta bufferra beteta dagoenean horra itzuliko da berriro: hala ere, honek CDan datuen tarte txikiak edukitzea adierazten duenez, oso gomendagarria da beti ere grabazioaren abiadura egokia aukeratzea burnfree- ren erabilera saihesteko, batizpat Audio CDetan (kasurik txarrenean batek tartea entzun dezake). Burnfree garai batean Burnproof gisa ezagutzen zen, baina MMC estandarraren zati bihurtu zenean aldatu zioten izena.
