And now, Introducing....

prpixel,

No, HDCD has been available in the pro world for a while now. They just changed the concept to tape to dramatically increase high frequency response and lower the noise floor. Apparently it's for real.

A friend of mine has a '67 Mustang with a working 8-track player, but he hardly ever uses it. He drives the car now and then, but the 8-track only has 2 tapes. Janis Joplin's "Kosmic Blues" and a Doobie Brothers. 

I'm tired of both of them, so I gave him some blank tapes from my stash. Five years ago! He still hasn't found a way to make some new tapes. 

"Apparently it’s for real."

Ivan, you can’t be serious. Look at the logo under the tape, DUBLY? And the tape, Kingston Duo?  April Fool’s joke, big time!

Look at the schematic; it uses some real technical terms such as "tape holder thingy" and "green soloniod nodule".  Oh, and the tapes are made of lead.  Yes, just want you want laying around the house for the little ones to chew on.  

Could be...They have their own sense humor about it one way or the other...
