CRDinfo, a <a href=http://www.cdrinfo.com/hardware/panasonic-lfd311/>questa pagina, </a> ha pubblicato la recensione del masterizzatore DVD Panasonic LF-D311 IDE DVD-RAM/R.<br><br>

Il masterizzatore, dotato di interfaccia EIDE come ormai quasi tutte le periferiche dedicate alla masterizzazione, permette la scritura di DVD-RAM e DVD-R, in modo da venire incontro alle esigenze di diverse tipologie di utenti.

La scelta di Panasonic riguardo agli standard di scrittura è abbastanza singolare, tanto da aggiungere confusione alla confusione già presente in questo campo. <br>
La possibilità infatti di utilizzare DVD-RAM (utilizzati in ambito quasi esclusivamente professionale soprattutto nel campo audio-video) e DVD-R può portare a indecisioni qualora ci si volesse accingere all'acquisto di un dispositivo di questo tipo. Riportiamo il dettaglio delle caratteristiche: <br><br>

Come è possibile notare alla voce riguardante i formati di scrittura supportati, manca l'importante voce DVD-RW, che sicuramente non avrebbe guastato, in quanto candidata a diventare molto diffusa nell'immediato futuro. Riportiamo le conclusioni dei test condotti da CRIinfo:<br><br>
