​​Consider a disk that has 209 cylinders, starting from index 0. At some time, the disk arm is at the 57th cylinder from the end moving from largest to innermost cylinder. There is a queue of disk access requests for cylinders 5, 40, 75, 195, 145, 203, 106 and 122. The R/W head of the disk uses the Circular Scan algorithm to reach the disk and access the data. The disk arm requires 1 msec to move between adjacent cylinders and 9 msec to move between the largest and innermost cylinder. The total seek time is _______.
