In a hard disk drive (HDD) or an electronic apparatus in which the HDD is wrapped with a foam resin sheet with a noise absorption effect and a metal outer casing to thereby damp noise, a sub-assembly wrapping body incorporating therein the HDD wrapped with a wrapping body composed of a slippery film sheet with foam resin sheets attached thereto is mounted into the metal outer casing through the slippery surface of the slippery film sheet. In order to insulate a noise generated from a recording and reproducing drive apparatus such as the HDD, the system for use with the HDD and the electronic apparatus can simplify the assembly process required when the HDD is loaded into the outer casing serving as a noise insulation box through a noise absorption member.
