Numerous studies [12], [126], [176], [13], [67], [76] have described techniques in support of a hiccup-free display assuming a homogeneous collection of single-zone disk drives. Single-zone disk drives provide a constant transfer rate. A multi-zone disk drive consists of a number of regions (termed zones) that provide a different storage capacity and transfer rate. For example, the Seagate Barracuda 18 provides 18 gigabyte of storage and consists of 9 zones (see Table 5.11). To the best of our knowledge, there are only four techniques in support of hiccup-free display with multi-zone disk drives: IBM's Logical Track [166], Hewlett Packard's Track Pairing [15] and USC's FIXB [65] and deadline driven ...
