Vcr is eating tapes

hi Hope you had good new year.
The problem is going to be with the head getting sticky and then the tapes get stuck to it instead of sliding smoothly over it.
Their two ways of solving this the one is buy a good head cleaner it comes in the form of a tape and you will get some cleaning sollution to put on the tape, however this option dont always work.
The way i have always done it is remove the case carefully not damaging anything make sure all screws are removed their might be even some hidden under the rubber bungs or even under stickers.
Once the case is removed place the video on flat ground the right way up and then look towards the back and you will either have 1 or two silver wheels this is where the video gets the picture from the tape.
These should be perfectly smoothe and shiny with not a mark on them as this will affect pictur quality.
What happens is you might have put a tape in that had a bit of grease or something sticky on it and this has becomes transfered onto the tape head.
Dont touch the sides but try tuenunig it by touching the top edge this should be free to the touch.
Also whilst spinning check under good light for any marks or grease.
You will need to get some cleaning alcahol and a dust free cloch you can use any cleaning fluid that isnt greasy like white spirits.
dab a bit on the cloth and then gently hold the cloth on the head whilst turning it with other hand do this several times then allow to dry thouroly leave it for about 15 min to evaporate then recheck.
It should be smooth with no scratche and no marks whatsoever.
then switch on without case on so you can look at whats happening make sure you touch nothing whilst doing this put tape in and try it if the problem is solved then put back together.
If not then its going to need a drive betl replacing but well worry about that later let me know ok should have solved your problem
