The DAT Machine I have in my office at work would disagree with you. I also own Minidisc players and recorders and several hundred cassettes, so yeah. please. But thanks for pointing me in the direction of r/minidisc.
But can I still buy Betamax cassettes? What about Memory Stick Duo's? What about new UMD's? How long before Bluray becomes a dead format on current trends? (I could go on here, but Sony's obssession with propriatory formats is legion and could fill several fucking books).
Is 'running their course' the new 'planned obsolence?'
You misread/misunderstood my post, and my comment was only based on your "Sony music formats" statement.
I will try again. Some formats just become tech. obsolete and some shouldn't have been brought to market. Betamax was the first home video format.
Minidisc was an attempt to replace compact cassette and had both technological and economic merits to exist at that time. Sony also invented 3.5" floppy disk and co-invented CD.
Do you use them today? Most likely not, but I bet your ass that you used it back in 80's,90's.
DAT was never meant to be used as the consumer format for music.
UMD, M-Stick Duo, VIta memory cards etc. I agree with you. These were clear cases where Sony was trying to force their own format over already established standards, and the fact of how long they persisted with them.
