Most of the affections related to open reel tapes can be treated with no further fuss, but some of them require to take precise action; Lab precision ovens and vertical laminar flow booth can help us to go through this and keep safe the reel information.
– Sticky Shed Syndrome (SSS) due to high temperature storage and humidity, the binder becomes gummy, and after a few seconds of playback, the heads becomes muddy. No mid and high frequencies are audible.
– Loss of Lubrication (LOL) The tape binder gets dry over the years, and when played back squeals affecting the recording. A re-lubricating process returns the original sound back.
– Broken parts or broken tape; this is a very common issue; sometimes it is the plastic reel which needs to be replaced, and sometimes the tape itself (specially acetate base tapes)
– Vinegar Syndrome; affects to acetate base tapes and it is one of the most severe harmful deseases. Priority transfer must be apply. When it happens, it can be set to dormant but never reversed.
– Inadequate winded tapes (edge frills, pack slip, spokes…); most of the cases are minor issues (depending on, some could bring Print Through problems. It requires to be properly handed before use to avoid also wow, flutter, breaks, etc.
– Mold; it needs definitely specialised hands over under laminar flow to avoid contamination spread, and manipulator health damage.

Professional software and hardware like Cedar Audio (c) allows us to remove the unwanted noises with no footprint into the recording.
– Hiss noise (maybe the most common noise in magnetic recordings)
– buzz, Hum (normally because of AC interferences)
– Print Through; based on storage issues; pre and post echoes could come up in the recording.

– Wow and flutter (some times related to badly calibrated or lack of manteineance devices, which produces inestable capstan working)
