  comment = {A short paper on some basic techniques used by disk controllers to
  improve throughput: seek optimization, request combining, request queuing,
  using multiple drives in parallel, scatter/gather DMA, data caching,
  read-ahead, cross-track read-ahead, write-back caching, segmented caching,
  reduced latency (track buffering), and format skewing. [Most of these are
  already handled in Unix file systems.]}
