Answer 1

How can you calculate the capacity of a Winchester disk given its density and speed? A disk has 10 recording surfaces. Each surface has 2000 tracks, each track has 512 sectors and each sector can store 1MB of data. Calculate the capacity of this disk. Ans:- Another term for hard disk drive. The term Winchester comes from an early type of disk drive developed by IBM that had 30 MB of fixed storage and 30MB of removable storage; so its inventors called it a Winchester in honor of its 30/30 rifle. Although modern disk drives are faster and hold more data, the basic technology is the same, so Winchester has become synonymous with hard. OR A type of disk storage device characterized by non removable or sealed disk packs; extremely narrow tracks; a lubricated surface that allows the head to rest on the surface during start and stop operations; and servo mechanisms which utilize a magnetic pattern, recorded on the medium itself, to position the head.Calculation of DISK Capacity Disk capacity = total number of surfaces * no. of tracks per surface * amount of data per track Total number of surfaces = 10 No. of tracks per surface = 2000 Amount of data per track = 512*1MBDisk Capacity = 10*2000*512*1 = 10240000 MB or = 81920000000000 bits
