What is the best way to delete or disable ( most expected) the field of a content type? We have several content types (features) on our Backend, now site Administrators (authors) and content managers need some field to be disabled when creating content. How I can manage it?
I heart about the 'field_permission' module but I'm not sure if that module can solve my problem.
What could be the best way to disable these fields? Is there some module or could some one explain where I should start?
Pseudo code are Welcome
Thank you in advance

Here's what I usually do. 


Find contents that have data for those fields you want to delete.(You can easily find it in DB)
Delete all contents found in step 1 or remove data from those contents.
Remove the field from content type.
