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]].
