Architectural innovation leaves the core technological concepts of the components intact but changes the way they are designed to work together, as in the change from removable
disk packs to the sealed Winchester disk drive architecture.
Positive oil circulation through the clutch and brake
disk packs is vital to cool and lubricate the friction surfaces.
For optimized protection--but at a higher cost than either tape or ATA disk--use RAID
disk packs, writing the data using redundancy (such as RAID 1+0 or RAID 5).
The company maintains who off-site vaults, one for storing magnetic media such as computer tapes,
disk packs, and floppy disks and another for storing microfilm and microfiche.
Some items that typically must be ordered include disk packs, magnetic tape for systems with a tape drive, labels for the collection list, printer ribbons, 8 1/2 11 report paper, and 11 14 "stock' paper.
These are generally kept on portable disk packs, which are not excessively bulky.
