1. Consider a disk with the following specifications: 16 surfaces, 256 sectors per track and 512 bytes per sector. Answer the following questions: a) what is the capacity of disk pack? b) what is the number of bits required to address the sector? c) If the format overhead is 32 bytes per sector, what is the formatted disk space? d) If the format overhead is 64 bytes per sector, how much amount of memory is lost due to formatting? e) If the diameter of innermost track is 21cm, what is the maximum recording density? f) If the diameter of innermost track is 21cm with 2KB/cm, what is the capacity of one track? g) If the disk is rotating at 3600 RPM, what is the data transfer rate? h) If the disk system has rotational speed of 3000RPM, what is the average access time with a seek time of 11.5msec ? 2. A disk pack has 19 surfaces and storage area on each surface has an outer diameter of 33 cm and inner diameter of 22cm. The maximum recording storage density on any track is 200 bits/cm and minimum spacing between tracks is 0.25mm. Calculate the capacity of disk pack
