I suppose that the larger capstan also reduces the chance of the tape being eaten.

If your car collector friend is ever in need of more blanks, let me know. I bought a bunch of them at an estate sale a few years back and realized I got more than I'd ever use. That said, they would still need the sensing tape and foam pads checked out and replaced if needed, those just go bad from age, not use.

Another thing I noticed is that the recorded level of the tapes also isn't necessarily the same tape to tape.

RE the carts and drive systems

If they'd have come out with the 8-track version of the ScotchCart with the retension ability and no moving parts other than the tape - and the cobalt and chrome tape formulations -
half of the 8 track's problems would have been solved.

Half of the remaining problems wd have been solved if they'd kept the drive roller in the player instead of in the tape like in a 4-track a k a broadcast cart.

Or if they'd have supported the RCA Sound Magazine from 1957

As far as the 8 track carousel players (and a few of the cassette versions)

You'd be surprised how many of those were either made for half-speed BGM tapes to
begin with or else were converted down to 1-7/8. My Dad brought one home in the late
70s when the airlines were getting ready to do the last conversions to 3/4 speed cassette (1-13/32 instead of 1-7/8 allowing for an hour on a side of a C-90).

By then, cobalt and then chrome tape had come out for loop cartridge configurations
(originally 7-1/2 Fidelity at 3-3/4 on a reel - so - conversely - 3-3/4 fideilty at 1-7/8)
so we'd make the ``masters'' on 3-3/4 - play it back on 7-1/2 - record the 8-track on
a normal recorder and then play it back on here.

Later on we got one for our `73 Woodie LTD that also ran half speed and normal speed
so now we could drive each other crazy with tapes that were upwards of 3 hours apiece.

We ran across a 3/4 speed cass player too - presumably so execs could hear their BGM
tapes in their car.

It seems to me the tapes wore down pretty fast. Even as a kid I would notice the highs disappearing after a few weeks of play.
And if you kept a case of tapes in your car, warm weather would soon mangle the cartridges, or the tape, or both.

Decent sound quality for its' main usage - the car. Mechanical quality was all over the ballpark. The rep firm that I worked for during that time sold hundreds and hundreds of those players. It was not unusable for a customer to get a shipment of 48 units and call us back the next day with another order. Was a wild time and a lot of fun. Normal road noise did help the sound quality.

Back in the heyday of 8 track, I had a pretty nice Pioneer 8 track recorder. I used to put all of my vinyl on 8 track for the car. My favorite part was "fitting" songs into the segments of the tape format. NOT. Eventually I just said to hell with it and let the songs have a CLICK in the middle of them. lol.

Agreed. Most car stereos back then didn't have the luxury of things like tweeters so full treble response wasn't needed.

My favorite part was pulling a tape out of the car player and having the tape remain in the player. Good times. Usually resulting in me yanking it all out and flinging it out the window.

blanks,
Q-8 carts would be nice as well as the 8-track demo carts with the clear tops.

8-track carousel player, I thought I'd seen everything.
Don't forget the 1-7/8 IPS background music versions that were out for a couple years which used the aforementioned clear-top 8-track carts instead of the Fidelipac types.

I'm continually amazed at the number of guys that will fork over good money for a title transcribed from a QR on a Fostex or Tascam four tracks at a time. The same guys will fork over even more for titles transcribed from e.g. SACD or DTS onto half-inch and THEN dubbed down to the Q-8 format before being loaded into the cart.

I have a boatload of genuine 1/4 inch BASF chrome dioxide loop tape and another boatload of 1/8 inch non-loop I bought on pancakes at fire sale prices a few years ago and like the above poster - realized I wouldn't live long enough to use it all up.

The Ampex recorder has is a larger capstan than most
So now I record on my specially adapted Revox A-77 reel deck - add in the stop tone and then cut apart one song or jingle at a time and load into the standard radio station stereo cart format for 7-1/2 IPS in e.g. Fidelipac (and others - esp Scotch with the stationary hubs and no pads to fall out) carts. All the classic radio guys buy `em up since they still have their old board and their old stereo cart players and etc.

For the stereo 8-track versions, I dub down so that single albums will play back at FF (7-1/2
IPS) and I teach guys how to clip the MUTE circuit on their players so they can hear `em.

This summer I'm starting to do the same thing for the 15/16 IPS Chrome and Metal cassettes for the guys who have the e.g. half speed Nakamichi 480 ZX and 3-3/4 IPS versions for the guys who have the e.g. Marantz 2 speed cassette deck.

Since I have this old Polyconcept 1/8 inch reel to reel
https://www.shopperschoice.com/item_item_1697858.html
that I fixed up special so I can just switch the A side and B side recording from an external source - other guys have been asking me to do stereo metal microcassette for the guys that have old Sony M1-PD TCMR-2's or M-80 stereo micro recorders because they use the same tape but use the same tracks in the opposite direction like a couple of the standard cassette half-speed or 3/4 speed background music companies used to do.

But even with no leader tape to worry about - and even with a little snapper contraption to attach the tape to the hub - I find that both my eyesight as well as my dexterity are at al all time low to be doing it.

Not to mention you can't even get NINE micron metal tape (for an MC-60) nevermind
SIX micron (MC-90) and still be able to get a playable tape out of it when you are done
meaning you are stuck with MC-50 or less.

Cassette C-90s for comparison are closer to 12 micron and normal 1-mil tape is 25.

Not to mention I got 2800 empty Revere Stereo Cartridge format shells from the central library here - untouched for nearly 60 yrs - which also uses the same tape:

So I'm getting ready to start that project up too.

Doing this goes under the same ``art'' clauses in copyright law as the guys who are putting e.g Maroon 5 or Nickelback onto a cylinder or Huey Lewis onto a 10-inch 78.

So I have fun.
