Description:
FIELD OF THE INVENTION 
     The invention relates generally to hard disc drives and more particularly to an impact shock absorbing hard drives. 
     BACKGROUND OF THE INVENTION 
     As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems. 
     Hard disc drives are a common source of field failures in information handling systems such as computer systems. Within a hard disc drive are several thin discs, i.e., magnetic media, each having an associated flying head, thus, making hard disc drives sensitive to impact. This is particularly true when the hard disc drive is removable and the impact occurs when the hard disc drive is separate from the computer system. 
     Upon impact, the heads of the hard disc drive may bounce and contact the discs. The discs may be either broken or scored by such impact. Loose particles may also result from such impact and become free to move around inside the hard disc drive and contact other parts of the hard disc drive thus causing new failures. Furthermore, such impacts may cause shock to the entire hard disc drive housing, not just to the heads. 
     Attempts to cushion hard disc drives against shock from impact include providing elastomer feet on the bottom or rest surface of the computer system for providing a cushioning effect of the portable computer housing on an associated support surface. These feet serve as friction surfaces to limit lateral movement of the computer system relative to its support surface. Cushioned mounts provide vibration damping but have not addressed the issue of where such mounts should be located to provide maximum protection from impact shocks. 
     SUMMARY OF THE INVENTION 
     Accordingly, a disc drive system which includes cushioning material positioned between the interior of disc drive housing and a disc drive advantageously provides a removable disc drive system which isolates shocks from the disc drive. 
     In one embodiment, the inventions relates to a disc drive system which includes a housing bottom, a mounting plate coupled to the housing bottom, and a disc drive coupled to the mounting plate via cushioning pieces. 
     In another embodiment, the invention relates to an information handling system which includes a processor, a memory and a disc drive system. The memory is coupled to the processor. The disc drive system includes a housing bottom, a mounting plate and cushioning pieces. The mounting plate is coupled to the housing bottom. The disc drive is coupled to the mounting plate via cushioning pieces. 
     In another embodiment, the invention relates to a removable hard drive which includes a housing top, a housing bottom, a mounting plate, a disc drive and cushioning pieces. The housing bottom is coupled to the housing top. The mounting plate is coupled to the housing bottom. The disc drive is coupled to the mounting plate via cushioning pieces.

     DETAILED DESCRIPTION 
     For purposes of this invention, an information handling system may include any instrumentality or aggregate of instrumentalities operable to compute, classify, process, transmit, receive, retrieve, originate, switch, store, display, manifest, detect, record, reproduce, handle, or utilize any form of information, intelligence, or data for business, scientific, control, or other purposes. For example, an information handling system may be a personal computer, a network storage device, or any other suitable device and may vary in size, shape, performance, functionality, and price. The information handling system may include random access memory (RAM), one or more processing resources such as a central processing unit (CPU) or hardware or software control logic, ROM, and/or other types of nonvolatile memory. Additional components of the information handling system may include one or more disk drives, one or more network ports for communicating with external devices as well as various input and output (I/O) devices, such as a keyboard, a mouse, and a video display. The information handling system may also include one or more buses operable to transmit communications between the various hardware components. 
     Referring to FIG. 1, information handling system  100 , includes a processor  102 , which is coupled to a bus  104 . Bus  104  functions as a connection between processor  102  and other components of computer system  100 . An input system  106  is coupled to processor  102  to provide input to processor  102 . Examples of input devices include keyboards, touchscreens, and pointing devices such as mouses, trackballs and trackpads. Programs and data are stored on a mass storage device  108 , which is coupled to processor  102 . Mass storage devices include such devices as hard disc drives, optical disks, magneto-optical drives, floppy drives and the like. Computer system  100  further includes a display  120 , which is coupled to processor  102  via a video controller  122 . A system memory  124  is coupled to processor  102  to provide the processor  102  with fast storage to facilitate execution of computer programs by processor  102 . It will be appreciated that other buses and intermediate circuits can be deployed within and information handling system operation of the information handling system. 
     Referring to FIG. 2, hard disc drive system  200  includes a hard disc drive  210  as well as a hard disc drive housing bottom  212 . The hard disc drive  210  is coupled to the hard disc drive housing bottom  212  via a mounting plate  220  and cushioning devices  222 , which are constructed of, e.g., foam. In a preferred embodiment, the foam includes double sided adhesive and mounting plate  220  is attached to the housing  212  via the double sided adhesive foam. The adhesive foam absorbs shock energy and effectively reduces the shock experienced by the hard disc drive  212  if the hard disc drive system  200  receives a shock such as when the system is dropped. Accordingly, the cushioning devices  222  provide vibration dampening to the hard disc drive  210  if the hard disc drive system  200  receives any type of impact. The housing bottom  212  includes positioning members  230  which are located substantially at the corners of the mounting plate  220 . The positioning members  230  interact with the cushioning devices  222  to provide additional vibration dampening. 
     Referring to FIGS. 3 and 4, hard disc drive system  200  includes a housing top  300 , the hard disc drive  210 , mounting plate  220 , cushioning devices  222  and housing bottom  212 .

Hard disc drive system  200  also includes a housing eject mechanism (not shown) which allows the removable hard disc drive system to be removed from the computer system. 
     The hard disc drive  210  is attached to the mounting plate  220  via screws that are in locations defined by a hard drive industry standard. In a preferred embodiment, the cushioning devices  222  are formed in spheres so that the screws may be easily passed through the middle of the cushioning pieces  222 . 
     Other Embodiments 
     Other embodiments are within the following claims. 
     For example, if additional vibration dampening needs arise, the cushioning material may be added to other locations within the hard disc drive housing. 
     Also for example, it will be appreciated that the cushioning devices may be fabricated from a variety of different materials so long as the material provides sufficient cushioning function. 
     Also for example, it will be appreciated that additional positioning members may be located to interact with the sides of the mounting bracket. In this case additional cushioning devices are added to the mounting bracket to interact with the additional positioning members. 
     Also for example, while the cushioning devices are shown as spherical, it will be appreciated that other shapes (such as, e.g., squares or rectangles) may be used. With these shapes, a hole may be located within the cushioning device to allow for mounting of the hard disc drive to the mounting bracket.
