Another design feature of the the ACR-25:
 
No metal to metal contact...
Let a plastic claw break or weld up some spools but 
nothing that would cause real mechanical  damage...

You could play 10 second spots back to back in the TCR as long as they  
were the only two spots on the break.   The rule of thumb we lived  by was you 
could play two ten seconds events on a break as long as they were  first and 
last, like a :10 promo going into a break and a :10 ID coming out of  it 
or, the only two things on the break. The midbreak in Hee Haw used to be an  
interesting challenge for the TCR a :30 local avail, a bumper off the reel to 
 reel a :10 local HFC CM, a :30 second spot a :10 ID and back to the show,  
often into a rollover in the next position on the tape. Always a little  
bit of nail biting, but the machine would do it.  We would play the  show on 
the TR-60, which was the SPU for the TCR and it would automate back  and 
forth between the R-R and the carts very cleanly.  You had to reject  out of the 
ID to get back to the show on time, because the position only  allowed :02 
for ID, but we did it every week with no problems.  
    I was told RCA tried a number of tricks to speed up  the cycle time, 
like dumping the tapes unrewound, and speeding up the belt,  but none of them 
proved practical. 
    The TCR had its eccentricities, but it we shouldn't  forget some of the 
pitfalls of the ACR like welding the reel to the inside of  the cart, 
breaking the little plastic hook that pulls the cart into position,  and oh, the 
column lamps failing just before a spot cluster. Also in the  machine we had 
here, the 5 HP blower was not above failing, usually late on  Sunday 
afternoon . . .

EPIS. Electronic Program Identification System.  Short burst of data after
 the start of message tone SOM.  Was not automated but very useful as you
 could easily see the next two carts loaded on a monitor just before a 
break.
 Saved us many times for loading the wrong cart.  The automation system had 
a
 bar code reader on the magazine transport which required a full scan of the
 magazine to know what was where.  It was random access but not quite so
 fast.  30 second spots were not a problem.  Could not cycle 10 second spots
 like the ACR (which could actually cycle 7.5 second spots continuously).
