The tr utility can only change one character into another one, in a
one-to-one relationship, or remove selected characters. Incidentally,
due to your use of double quotes this is a no-op ("\t" and "\\t" are the
same).
None of the utilities that are part of coreutils can do what you want,
but you can use sed, for example:
$ sed 's/\t/\\t/g' <head.txt
