Re: F/S:BRAND NEW reel to reel recording tape
Howdy!
"Pro" level open reel recording tape is made in 1/4" 1/2" 1" and 2" widths...most commonly on a 10 1/2" reel which translates out to 2500 feet...roughly 16 1/2 minutes at 30ips or 33 minutes at 15ips.
Based on the descriptions in metric & without pictures...that sounds like cassette tape or more likely, waaaaaaaaay old 'consumer' grade open reel tape. Maybe from the mid or late '70s? TDK hasn't made open reel tape in almost two decades...
Honestly man, I'd put it on Fleabay or better yet...toss it. If it was some super groovy unused Quantegy GP9 or 456 then I'd be PayPallin' you already!
Peace.
