About the Maxell Professional DAT R-DA The Maxell Professional R-DA is Maxell's studio-grade blank DAT tape, designed specifically for professional master recording, broadcast, and critical archival applications. It uses Maxell's DAT Ceramic Armor metal particle formulation - coated to deliver 2,600 Gauss of magnetic energy - and is built to tighter manufacturing tolerances than the consumer DM series. Like all professional-grade DAT tapes, the R-DA comes in a large rigid protective case rather than individual shrink-wrapped packaging, as is standard for studio media. Technical Specifications Grade: Professional / Studio Master Formulation: Ceramic Armor (CA) metal particle - 2,600 Gauss output Construction: 5-layer tape with smooth base film, ceramic armor layer, and dust-resistant backcoating Shell: Large rigid professional case (not individually shrink-wrapped) Tape width: 3.81mm (4mm) Recording modes: Compatible with 32 kHz, 44.1 kHz, and 48 kHz / 16-bit Available lengths: 65 and 95 minutes Who Is This Tape For The R-DA is the right choice for studio engineers, broadcast professionals, and archivists who need a professional-specification DAT tape for master recordings. Its tighter manufacturing tolerances and higher-output formulation make it preferable for critical applications where dropout performance and consistency across an entire reel matter. Note that these tapes are not individually sealed - they come in the standard professional studio bulk packaging. Condition New Old Stock (NOS) - never recorded, in original professional studio packaging. Not individually shrink-wrapped, as is standard for studio-grade DAT media.
