Line 4:

While sequential access memory is read in sequence, arbitrary locations can still be accessed by "seeking" to the requested ___location. This operation, however, is often relatively inefficient (see [[seek time]], [[rotational latency]]).

Magnetic sequential access memory is typically used for [[secondary storage]] in general-purpose computers due to their higher density at lower cost compared to RAM, as well as resistance to wear and [[non-volatility]]. ExamplesExample of SAM devices still in use includeis [[hard disk]]s, [[CD-ROM]]s andonly [[magnetic tape]]s. Historically, [[drum memory]] has also been used.
