Can we finally put Reel to Reel out of its misery? Put it to rest people.

... We should also note that is a myth that reel to reel heads wear. Yes the metal heads used on professional decks wear but then they are still manufacturing new heads for pro decks.

What's your point? First you say one thing, then another. Either way, there's no question that tape heads are subject to wear. It's not a "myth."

What does wear are the tapes themselves every time you play them, so more times than not any used tape you buy on the market has lost it’s higher frequencies and doesn’t sound too good. This is because as a tape sheds overtime it changes the azimuth.

There are several ways tape can lose HF and wear is only one of them. Exposure to a magnetized tape path is another - that's the function of a demagnetizer. But I'd sure like to know why you think tape wear changes azimuth.

The heads used in consumer decks are the same heads used in cassette decks like Nak. 

That's actually impossible. Cassette and reel are two different formats, two different tape widths.

Funny enough one of the advantages of VHS tape for example is that it does not come in direct contact with the heads, so VHS heads and VHS tape does not wear ...

A VHS tape deck wraps the tape around a rotary spinning tape head, which gives it a high "write speed" relative to the speed of tape travel. There is definitely contact between tape and head and wear is the result.

While I agree with a lot of what you posted, its a simple fact that heads wear- I've replaced many of them in my time, on cassette, consumer RTR and pro machines as well.

My first and only deck was a Pioneer RT-1011L, which I would probably still have except for one thing: head wear. The heads had obvious visible wear at a time when I was too broke to replace them. So I wound up practically giving it away. One of the dumbest and most regrettable moves of my entire audio career. So yes indeed tape heads do not defy the laws of physics. Reel to reel tape heads definitely do wear.

So, many of the consumer reel to reel decks sold on the market like cassette decks were manufactured with heads that never wear down. For that reason ferrite heads for example cannot be relapped. They never develop a flat spot. Since the ferrite is encased in glass unlike metal heads, they can be polished but not reshaped. Also to clarify, head wear and head failure are not the same. Ferrite can go bad.

Mostly from wear on the spools. Tape played the first time will not have the same azimuth as the tape played the 200th time.

VHS rewinders solved a problem that did not exist. Because of the nature of moving heads, VHS tape floats close to the heads but do not need to make direct contact unlike linear tracks. Early VCRs would load and wrap the videotape virtually completely around the video head (leftover technology from the U-MATIC format) leading to premature wear. Under normal circumstances VHS tape will never "wear out" or "fade". That is a common myth spread around from the ads to "save your tapes".

I have been restoring reel to reel and cassette tape machines since 1980 when plenty where new. I run a service / restoration shop in Brooklyn NY for tape machines. I’ve never been busier with high end, home & pro recording studio folks.
Right now there is a trend of selling broken reel machines for outta-sight prices, then needing repairs after fact.

Heads do wear, but reconditioning / lapping gives many years of life.

Just a little Reel vs Cassette comparison:
There are 3 companies that manufacture new reel to reel tape. On the cassettes front I’m pretty sure no one is making CrO2 tape anymore. and that is the only tape that has the low noise floor and HF response the sounds good with music.

Going back to the beginning of this thread. cassettes no matter how well the calibration on the machine is will never surpass the quality of Reel to reel for so many reasons.
If you would like to discuss further feel free to contact me .

....after looking at this thread, a lot of this was discussed
