ATR Magnetics Blank Recording Tape

ATR Magnetics was founded in 1996 by Michael Spitz, a former Ampex employee with decades of experience in the magnetic tape industry. Spitz established ATR with a specific goal: to produce analog recording tape that matched or exceeded the performance of the Ampex 456 and 499 formulations that had defined professional studio recording for a generation. Beginning commercial tape production in 2005 from a manufacturing plant in York, Pennsylvania, ATR Magnetics became the only current manufacturer of professional analog recording tape in the Western Hemisphere.

ATR's Master Tape - formulated to closely resemble the beloved Ampex 456 high-output formula - delivers a +6 dB high-output specification with industry-standard bias compatibility. The company's tapes are used in professional recording studios, mastering facilities, film production companies, and archival institutions worldwide. ATR also produces an MDS-36 formulation (1 mil thickness for high-speed applications) and a line of ferric oxide and cobalt cassette tapes.

ATR Magnetics was the first tape manufacturer in the analog revival era to offer colored flanges, reintroduce 1-mil tape, release product on 7-inch reels, and launch a dedicated cassette tape line - making them a pioneer in the resurgence of professional analog media that accelerated through the 2010s and 2020s.
