Title: Sorting/merging process method for disk data
Inventor: AOKI KIYOSHI
IPC: G06F7/24
Filed: 1988-11-17
Abstract: PURPOSE:To reduce the shift frequency of a magnetic head between cylinders and also to shorten the seeking time by setting the magnetic head on one of both cylinders to continuously perform a comparing process for sorting and merging until just a single piece of data remains on the other cylinder then shifting the head to the other cylinder to perform the same comparing process. CONSTITUTION:A cylinder control part 1 gives an instruction to a buffer control part 2 to give an access to each cylinder via a magnetic head. At the outset (n - 1) pieces of data are read out of one of both cylinders and sent to (n) pieces of buffers together with a single piece of data read out of the other cylinder and sent to these buffers respectively. Then these (n) pieces of data are compared with each other for sorting and merging via a comparing process part 4. Thus the preferential data is outputted and the data on the cylinder where the magnetic head is set are fetched and compared repetitively with each other. When just a single piece of data remains on the other cylinder out of those (n) pieces of data, the magnetic head is shifted to the other cylinder to perform the same process again. Thus it is possible to reduce the shift frequency of the magnetic head between both cylinders and also to shorten the seeking time.
