   When I record or play back a tape on my VCR (Sears brand), The unit
   makes a rather annoying squealing sound like a cricket.  Certainly
   this can't be normal.  The VCR is about two years old.  Don't remember
   this being a problem until recently.  There is no audio or video
   distortion.  How does one eliminate this noise?

Some VCRs control the speed of the head drum by providing a motor that
wants to turn it slightly too fast and using an electromagnetically
controlled brake.

Some such brakes are eddy current brakes [no mechanical contact] but
others are mechanical [ecch].

Probably you need to have it done, but it shouldn't be too expensive.
