Memory Unit - 5 Coa PDF | PDF | Computer Data Storage | Random Access Memory Consider a disk with an average seek time of 4ms, rotation speed of 15,000 rpm, and 512 byte sectors with 500 sectors/track. we wish to read a file consisting of 2500 sectors for 1.28 mbytes. estimate the total time for the transfer. assume that the file is stored as compactly as possible. —theory is based on abstract algebra and the details are beyond the scope of this course —widely used for storage media including hard disks —specific technique is called “cross interleave reed solomon coding” (circ). Ch 6 external memory free download as pdf file (.pdf), text file (.txt) or read online for free. the document discusses various types of external memory including magnetic disk, optical storage like cd rom and dvd, and magnetic tape. Pulses are sent to the write head, and magnetic patterns are recorded on the surface below, with different patterns for positive and negative currents. an electric current in the wire induces a magnetic field across the gap, which in turn magnetizes a small area of the recording medium.
