The dangerous world of Reel-to-Reel Tape

thanks @mijostyn for the response.

it’s a huge effort these days to have a top tape deck and acquire the proper media, and few have the commitment to do it. but it does deliver fully.

it’s kind of a crazy thing, to be honest about it.

dabbling in more consumer or broadcast/prosumer decks is not the same as a fully sorted master recorder either. and then there are hot rodded master recorders, and then ones with the best possible output electronics....the MR-70. so it takes alot to touch the stars with tape. but it’s awesome.

the air cooled 911’s don’t make sense either, but i get that fully. although i did the 16’ CS2 thing myself in my Porsche phase a few years ago. i smiled every time i sat down in it.

As I'm getting older I appreciate convenience whenever possible.  This is also true regarding audio, where I stream most of my music.. However,  I still enjoy listening to my Nakamichi ZX7 from time to time.  It produces far more distortion than my digital sources, yet still sounds good after 40 years.   I used to own a Revox B77 Mark II and before that a Revox A77.  Both were great sounding decks, but I sold the A77 because it was not very reliable. The B77 on the other hand was very reliable.   IMHO there's something enjoyable about handling physical media that is absent with streaming technology.  So I enjoy the best of both worlds by using both technologies. 

how long do recorded magnetic tapes (here: R2R, but also 8 track, cassette, VHS, etc) LAST before they loose their information?

@kraftwerkturbo That depends on storage. They need to be stored in a low humidity environment to prevent shedding of the oxide on which the recording exists. It that is done the tape will last decades with ease.

For this reason its better to store tapes in an attic rather than a basement! Its also a good idea to store the tape in a plastic bag in its box, along with a packet of Silica Gel.

@kraftwerkturbo It depends.

I purchased a case (10 reels) of Maxell 35-180 UD tape in 1981.  A few years later, I purchased two cases (20 reels) of "Ampex GM-3600 Grand Master Professional Recording Tape." 

From the mid 90’s to the mid 2000's, my R2R sat mostly unused, but I would play a reel on rare occasions.  Around the mid 2000’s, I noticed my Ampex tapes started to sound muddy and were leaving a lot of residue on the tape heads, pinch rollers, and transport mechanism so I had to stop using them (because they sounded like crap).

My Maxell reels are still playing just fine.

I was referring to the lifetime of the RECORDINGS ON the tape. I heard that also vibrations (for example keeping it in the car) will erode the quality and reorient the magnetic particles. My VHS tapes (20 years?) have lost pretty much everything, barely useable.
