Analog open-reel tape Recording The Masters LPR90 1/4" (6.35 mm) — 3608 ft length

Recording The Masters LPR90 1/4" (6.35 mm) open-reel tape, 3608 ft length, is a professional analog magnetic tape designed for playback, archival and long-format recording on compatible reel-to-reel machines. The LPR90 formulation provides a balance between low noise and stable magnetic properties, making this tape suitable for transferring analog masters, creating reference copies and continuous session recordings that require extended runtime without frequent reel changes.

Advantages

The tape's LPR90 chemistry delivers consistent bias response and reduced background noise compared with standard consumer formulations, while maintaining a stable mechanical construction across the full 3608 ft length. Manufactured to professional tolerances, the tape offers uniform coating and tension behaviour to minimise dropouts and speed-related artefacts during playback. Its 1/4" (6.35 mm) width and long length enable extended recording times on standard 1/4" transports, reducing the need for reel swaps during transfers or long sessions.

Suitable for

• Studio archival transfers of master tapes and analog collections
• Creating mastering reference copies and safety copies
• Long-format continuous recording and live session capture
• Playback and quality checks on professional reel-to-reel machines

How to use

Handle the tape on a clean, dry surface and avoid touching the coated side. Load the tape onto a compatible 1/4" reel-to-reel machine following the manufacturer's loading and tensioning procedure. Set appropriate bias and equalisation settings for LPR90 to optimise frequency response and noise performance; consult the tape machine manual for recommended settings. During playback or recording, monitor tape tension and alignment to prevent edge skew or flutter. After use, store reels on hubs or in appropriate archival boxes in a cool, dry environment away from magnetic fields.

Usage recommendations

For best long-term results, use calibrated bias and EQ settings suited to LPR90, perform gentle head cleaning before sessions, and allow newly wound reels to relax for a short period to stabilise tension. Store finished reels vertically in a temperature-controlled, low-humidity environment and keep away from strong magnets and direct sunlight.
