Abstract
A method of reclaiming a head suspension includes detaching a slider 225 from a tongue 221 of the head suspension and removing an adhesive 227 remaining on the tongue 221. Removing the adhesive 227 remaining on the tongue 221 includes feeding a solvent 243, which promotes the removal of the adhesive 227, to a part of the tongue 221 where the adhesive 227 remains and promoting the removal of the remaining adhesive 227 from the tongue 221 by applying physical energy to the adhesive remaining part on the tongue 221. The physical energy is produced by heating, supersonic vibration, and the like. The method easily removes the adhesive 227 from the tongue 221 without directly applying mechanical force to the tongue 221, thereby improving yields.
