An access method refers to the way that data is retrieved based on the file organization in use, such as sequential or direct access. It is not the same thing as a file organization, which refers to how the data is physically stored on a storage medium. Access methods are also not specific to disk storage and can be used with tape storage as well. The series of steps involved in retrieving data from a disk, including seek time, head switching, rotational delay, and transfer time, are part of the process of accessing data using a particular access method. The access method is established after the file organization is chosen.
