Abstract
A damper which is adhered to the head suspension of a disc drive, which comprises a constraint layer/viscoelastic layer laminate, wherein the viscoelastic layer is temporarily provided with a release sheet that is removed on use so that the damper may be adhered to the head suspension, the side of the release sheet in contact with the viscoelastic layer having been treated with a non-silicone releasing agent, preferably a long-chain alkyl type or fluoroacrylate type releasing agent. No silicone is transferred to the viscoelastic layer so that silicone gas generation causing destruction of the memory layer of a disc can be prevented.
