Addressing
Different from the “regular” disk method.
Each second of playing time on a CD is divided into 75 sectors. Each sector holds 2 Kilobytes of data. Each CD-ROM contains at least one hour of playing time.
==> The disc is capable of holding at least 60 min * 60 sec/min * 75 sector/sec * 2 Kilobytes/sector = 540, 000 KBytes
Often, it is actually possible to store over 600, 000 KBytes.
Sectors are addressed by min:sec:sector e.g., 16:22:34
