Abstract

A data storage device (DSD) is assembled with a flexible sheet of barrier material covering at least a portion of the top cover and/or bottom base of the DSD enclosure, whereby a layer of air is between the sheet of barrier material and the cover and/or base. Polyvinlyidene chloride (PVDC) may be used as the barrier material. A wrap-around structure may be used for the barrier material, enveloping the DSD so that an open end can be positioned open to a primary direction of airflow, such that a respective layer of air is created between the barrier material and each of the cover and/or base. An adhesive may be positioned around the outer edge 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 therebetween.

First claim

What is claimed is:

1. A data storage device assembly comprising:
a data storage device comprising an enclosure comprising a bottom base and a top cover coupled with said base; and
a flexible sheet of barrier material configured as a wrap-around structure having at least one open end and enveloping said data storage device on at least four sides;
wherein one said open end of said wrap-around structure is open to a primary direction of gas flow such that a layer of gas inflating said sheet comprises (a) a first layer of gas between said cover and a first corresponding portion of said sheet and (b) a second layer of gas between said base and a second corresponding portion of said sheet.

2. The data storage device assembly of claim 1 , wherein said barrier material comprises polyvinylidene chloride (PVDC).

3. The data storage device assembly of claim 1 , wherein said barrier material consists of polyvinylidene chloride (PVDC).

4. A data storage system assembly comprising:
a data storage device assembly comprising:
a data storage device comprising an enclosure comprising a bottom base and a top cover coupled with said base,
a flexible sheet of acoustic-absorbing and/or acoustic-insulating barrier material covering at least a portion of said cover and/or said base, and
a layer of gas between said sheet of barrier material and said portion of said cover and/or said base; and

a cooling fan that flows gas between said sheet of barrier material and said portion of said cover and/or said base, thereby generating said layer of gas.

5. The data storage system assembly of claim 4 , wherein said barrier material comprises polyvinylidene chloride (PVDC).

6. The data storage system assembly of claim 4 , wherein said sheet of barrier material is configured as a wrap-around structure having at least one open end and envelopes said data storage device on at least four sides.

7. The data storage system assembly of claim 6 , wherein one said open end of said wrap-around structure is open to a primary direction of gas flow such that said layer of gas comprises (a) a first layer of gas between said top cover of said enclosure and a first corresponding portion of said wrap-around structure and (b) a second layer of gas between said bottom base of said enclosure and a second corresponding portion of said wrap-around structure.

8. The data storage system assembly of claim 4 , further comprising:
an adhesive positioned around an outer edge of said top cover of said enclosure of said data storage device and adhering said barrier material to said top cover.

9. The data storage system assembly of claim 4 , further comprising:
an adhesive bond line around an outer edge of said top cover of said enclosure of said data storage device and adhering said barrier material to said top cover, wherein said adhesive has a break in said bond line thereby allowing said gas layer to fill space between said barrier material and said top cover.

10. The data storage system assembly of claim 4 , further comprising:
an adhesive positioned around an outer edge of said bottom base of said enclosure of said data storage device and adhering said barrier material to said bottom base.

11. The data storage device assembly of claim 4 , further comprising:
an adhesive bond line around an outer edge of said bottom base of said enclosure of said data storage device and adhering said barrier material to said bottom base, wherein said adhesive has a break in said bond line thereby allowing said gas layer to fill space between said barrier material and said bottom base.

12. A method of assembling a data storage assembly, the method comprising:
enveloping a data storage device on at least four sides with a flexible sheet of polyvinylidene chloride (PVDC) material configured as a wrap-around structure having at least one open end, such that gas is between said sheet and at least a portion of said data storage device; and
housing said data storage device in a system enclosure that houses a cooling fan, such that one said open end of said wrap-around structure is open to a primary direction of gas flow generated by said cooling fan.

13. A data storage device assembly comprising:
a data storage device comprising an enclosure comprising a bottom base and a top cover coupled with said base;
a flexible sheet of barrier material covering at least a portion of said cover and/or said base;
an adhesive positioned around an outer edge of said cover and/or of said base and adhering said barrier material to said cover and/or said base; and
a gas inflating said sheet around said portion of said cover and/or said base.

14. The data storage device assembly of claim 13 , wherein:
said adhesive forms an adhesive bond line around said outer edge of said cover and/or said base; and
said adhesive has a break in said bond line thereby allowing said gas to fill space between said barrier material and said cover and/or base.

15. A method of assembling a data storage assembly, the method comprising:
covering, with a flexible sheet of polyvinylidene chloride (PVDC) material, at least a portion of a data storage device; and
applying an adhesive around an outer edge of said portion of said data storage device to adhere said sheet to said portion, wherein said adhesive has a non-continuous section to allow a layer of gas to fill space between said sheet and said portion of said data storage device.
