摘要： A disk drive that includes a head disk assembly (HDA) having a disk drive base, and a printed circuit board assembly (PCBA) in communication with the HDA. The invention further includes an acoustic damping assembly placed between the disk drive base and the PCBA. The acoustic damping assembly includes first and second acoustic absorption layers having major surfaces, an acoustic barrier layer placed in between the major surfaces, and the major surfaces and the acoustic barrier layer are fixed in a stacked relationship.

摘要： A disk drive that includes a head disk assembly (HDA) comprising a base having a top base surface and a bottom base surface, and a top cover secured to the top base surface; a printed circuit board assembly (PCBA) in communication with the HDA and comprising a first PCBA surface and a second PCBA surface wherein the first PCBA surface faces the bottom base surface; and a bottom cover fastened to and substantially covering the bottom base surface. The invention further includes an acoustic damping shield assembly placed between the bottom cover and the second PCBA surface, wherein the acoustic damping shield assembly comprises first and second acoustic absorption layers having major surfaces; an acoustic barrier layer placed in between the major surfaces; and the major surfaces and the acoustic barrier layer are fixed in a stacked relationship.
