Default Re: Sony TC-645 1/4 Track R2R Erase Head & Issues

Is it missing or did Sony at some point conclude that the wear on the erase head was negligible and consequently omit it from later designs? After all, the wear wouldn't take place in the actual gap area but slightly left of it.
That's the motor auto shut off in the TC-377, the motors auto shut off isn't fitted in the TC-645 on that side, the TC-645's FF & RW motors auto shut off switch is linked to the tension arm on the right hand side of the tape path.
