Embodiment Construction

[0018] A method of digital data storage device assembly is described. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the invention described herein. It may be evident, however, that the embodiments of the invention described herein may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to avoid unnecessarily obscuring the embodiments of the invention described herein.

[0019] Physical Description of an Exemplary Operating Context

[0020] Embodiments may be used in the context of digital data storage device (DSD) components, such as hard disk drives (HDDs), that may be housed within, for example, a larger enclosure or "rack." Therefore, according to one embodiment, figure 1 A plan view showing HDD 100 is shown in to illustrate an exemplary operating context.

Abstract

The invention is entitled "Packaged Data Storage Device for Vibration Reduction". The present invention discloses a data storage device (DSD) that is assembled using a flexible sheet of barrier material that covers the top cover and / or bottom base of the DSD case. At least a portion, whereby the air layer is located between said sheet of barrier material and said cover and / or base. Polyvinylidene chloride (PVDC) can be used as the barrier material. A wrap-around structure may be used for the barrier material, the wrap-around structure surrounding the DSD such that the open end may be positioned to open into the main direction of air flow so that the gap between the barrier material and the cover and / or base A respective air layer is formed between each of the seats. Adhesive may be positioned around the outer edges of the cover and / or base to adhere the sheet of barrier material to the respective cover and / or base while allowing the air layer to fill the space in between. space.

Description

technical field [0001] Embodiments of the invention may relate generally to data storage devices, and more particularly to reducing the effects of vibrations within data storage devices. Background technique [0002] A hard disk drive (HDD) is a non-volatile storage device that is housed in a protective housing and stores digitally encoded data on one or more platters with magnetic surfaces. When the HDD is in operation, each magnetic recording disk is spun rapidly by a spindle system. Data is read from and written to a magnetic recording disk using a read / write head positioned by an actuator over a specific location on the disk. Read-write heads use magnetic fields to read data from and write data to the surface of a magnetic recording disk. A write head utilizes current flowing through a coil, thereby generating a magnetic field. Electrical pulses are sent to the write head in different patterns of positive and negative current. Current in the coil of the write head in...
