A disk drive includes a disk drive enclosure and a disk rotatably mounted to and within the disk drive enclosure. A desiccant canister is in fluid communication with the disk drive enclosure. The desiccant canister includes a canister housing and a desiccant material within the canister housing. The desiccant canister includes a water absorption restriction that limits a steady-state hourly water absorption rate of the desiccant to not exceed 2% of the desiccant's total capacity for water absorption.
1. A disk drive comprising: a disk drive enclosure;a disk rotatably mounted to and within the disk drive enclosure; anda desiccant canister in fluid communication with the disk drive enclosure, the desiccant canister including: a canister housing;a desiccant material within the canister housing, the
1. A disk drive comprising: a disk drive enclosure;a disk rotatably mounted to and within the disk drive enclosure; anda desiccant canister in fluid communication with the disk drive enclosure, the desiccant canister including: a canister housing;a desiccant material within the canister housing, the desiccant material defining a total capacity for water absorption, anda water absorption restriction that limits a steady-state hourly water absorption rate of the desiccant material to not exceed 2% of the desiccant material's total capacity for water absorption. 2. The disk drive of claim 1 wherein the desiccant canister is in fluid communication with the disk drive enclosure by the canister housing including an opening that faces into the disk drive enclosure. 3. The disk drive of claim 2 wherein the canister housing is at least partially disposed within the disk drive enclosure. 4. The disk drive of claim 2 wherein the opening in the canister housing is the water absorption restriction. 5. The disk drive of claim 4 wherein the opening is cylindrical with a diameter in the range of 0.25 mm to 2 mm. 6. The disk drive of claim 2 wherein the water absorption restriction comprises a pressure sensitive adhesive (PSA) polymer layer that has an outer periphery and that is disposed within the opening in the canister housing, the outer periphery of the PSA polymer layer being disposed with a finite clearance from the opening in the canister housing, said clearance allowing water absorption between the PSA polymer layer and the opening in the canister housing. 7. The disk drive of claim 1 wherein the canister housing comprises a hard plastic material having a thickness in the range of 0.5 mm to 5 mm. 8. The disk drive of claim 1 wherein the water absorption restriction comprises a semi-permeable barrier layer. 9. The disk drive of claim 8 wherein the semi-permeable barrier layer comprises a semi-permeable activated carbon layer having a thickness in the range of 0.3 mm to 2 mm. 10. The disk drive of claim 8 wherein the desiccant material comprises a solid monolith of desiccant material, and the semi-permeable barrier layer is a coating on the solid monolith of desiccant material. 11. The disk drive of claim 10 wherein the coating comprises a semi-permeable polymer film or a latex paint, having a thickness in the range of 10 microns to 100 microns. 12. The disk drive of claim 1 wherein the steady-state hourly water absorption rate of the desiccant material does not exceed 0.20% of the desiccant material's total capacity for water absorption. 13. A desiccant canister for a disk drive, the desiccant canister comprising: a canister housing;a desiccant material within the canister housing, the desiccant material defining a total capacity for water absorption, anda water absorption restriction that limits a steady-state hourly water absorption rate of the desiccant material to not exceed 2% of the desiccant material's total capacity for water absorption. 14. The desiccant canister of claim 13 wherein the desiccant canister includes an opening for water absorption. 15. The desiccant canister of claim 14 wherein the opening in the canister housing is the water absorption restriction. 16. The desiccant canister of claim 15 wherein the opening is cylindrical with a diameter in the range of 0.25 mm to 2 mm. 17. The desiccant canister of claim 14 wherein the water absorption restriction comprises a pressure sensitive adhesive (PSA) polymer layer that has an outer periphery and that is disposed within the opening in the canister housing, the outer periphery of the PSA polymer layer being disposed with a finite clearance from the opening in the canister housing, said clearance allowing water absorption between the PSA polymer layer and the opening in the canister housing. 18. The desiccant canister of claim 13 wherein the canister housing comprises a hard plastic material having a thickness in the range of 0.5 mm to 5 mm. 19. The desiccant canister of claim 13 wherein the steady-state hourly water absorption rate of the desiccant material does not exceed 0.20% of the desiccant material's total capacity for water absorption. 20. The desiccant canister of claim 13 wherein the water absorption restriction comprises a semi-permeable barrier layer. 21. The desiccant canister of claim 20 wherein the semi-permeable barrier layer comprises a semi-permeable activated carbon layer having a thickness in the range of 0.3 mm to 2 mm. 22. The desiccant canister of claim 20 wherein the desiccant material comprises a solid monolith of desiccant material, and the semi-permeable barrier layer is a coating on the solid monolith of desiccant material. 23. The desiccant canister of claim 22 wherein the coating comprises a semi-permeable polymer film or a latex paint, having a thickness in the range of 10 microns to 100 microns.
