Tape Head demagnetiser

[srini196812]

I am located in Mumbai and am looking for a tape head demagnetiser for my cassette deck (onkyo). will be willing to come and pick up if it is in mumbai. Does any body know where i can source one of these from?

bias current and recording process (whenever used) takes care of demagnetizing. I have used a demagnetizer but to me it does not seem to offer any benefits.
