A • Average seek time is a true statistical random average of at least 5,000 measurements of seeks between random tracks, less overhead. • Full-stroke seek time is one-half the time needed to seek from the first data cylinder to the maximum data cylinder and back to the first data cylinder.
  • Page 15 U8 Family Product Manual, Rev. A • Seek Mode During seek mode, the read/write actuator arm moves toward a specific position on the disc surface and does not execute a read or write operation. Servo electronics are active. Seek mode power rep- resents the worst-case power consumption, using only random seeks with read or write latency time.
