a first link part arranged between the plurality of folding parts to enable the plurality of folding parts to be folded with one another.
6. The top cover arrangement according to claim 1 , further comprising:
a joint part for mounting a second folding part of the plurality of folding parts that is closest to a rear most portion of the drawer chassis to the rear-most portion of the drawer chassis.
7. The top cover arrangement according to claim 6 , wherein a bottom of the joint part is adhered to the flexible substrate and jointed to the second folding part via a second link part.
8. The top cover arrangement according to claim 1 , wherein the flexible substrate is made of polyester material, and the plurality of folding parts are polycarbonate membrane.
9. The top cover arrangement according to claim 1 , wherein:
the top cover arrangement covers the plurality of rows of when the plurality of rows are fully pushed into the drawer chassis;
the top cover arrangement covers the plurality of rows when the plurality of rows are pulled out of the drawer chassis without exposing one or more disks of the one or more disks;
the top cover arrangement is lifted to fold at least a part of the plurality of folding parts so as to expose at least one row of the plurality of rows when the plurality of rows are pulled out of the drawer chassis to expand or replace one or more disks of the one or more disks.
10. The top cover arrangement according to claim 1 , further comprising at least one of the following:
a functional indicator indicating the functional state of the disks;
an operational indicator promoting the user's operational manner; and
a warning indicator providing warning information.
11. A disk drive storage unit, comprising:
a drawer chassis comprising one or more midplanes arranged successively along a pulling direction of the drawer chassis, and accommodating one or more disks that are organized in a plurality of rows with each row placed against a corresponding midplane;
a fan accommodated in the drawer chassis and positioned between the plurality of rows and a rear-most portion of the disk drive storage unit, the fan being arranged along a direction perpendicular to the pulling direction and generating suction air for dissipating heat from the one or more disks; and
a top cover arrangement for the storage comprising:
a flexible substrate covering the one or more disks; and
a plurality of folding parts mounted on the flexible substrate such that each folding part corresponds to a row of the plurality of rows wherein the plurality of folding parts are configured to be at least partially folded to expose at least one row of the plurality of rows of one or more disks such that folding each folding part will expose the corresponding row of the plurality of rows in response to the disks being pulled out of the drawer chassis while limiting air flow above at least one row of the one or more disks that is unexposed, the plurality of rows and the fan being connected to each other via a cable configured to maintain an electrical connection between the drawer chassis and a corresponding circuit when one or more rows disks are pulled out of the drawer chassis.
12. The storage of claim 11 , wherein the plurality of folding parts are arranged abreast on the flexible substrate along a pulling direction of the drawer chassis and within the range of the flexible substrate.
13. The storage of claim 11 , wherein the top cover further comprises: a first notch arranged at an edge of the flexible substrate closest to a front-most portion of the drawer chassis, and a second notch arranged on a folding part of the plurality of folding parts closest to the front-most portion of the drawer chassis, wherein the first notch and the second notch are matched with each other to facilitate lifting the top cover arrangement in use.
14. The storage of claim 11 , wherein the folding part of the plurality of folding parts that is closest to the front-most portion of the drawer chassis has a dimension smaller than that of at least one other folding part of the plurality of folding parts.
