medium along with additional information that the library
controller uses to manage storage and retrieval. The format of the
additional information is unique and is hidden from the initiator
during normal read or write operations. This additional
information is often used to identify the physical location of the
blocks of data and the address of the logical block, and to provide
protection against the loss of the user data.
The address of the first logical block is zero. The address of the last
logical block is [n-1], where [n] is the number of logical blocks
available on the medium. A Read Capacity command may be
issued to determine the value of [n-1]. If a command is issued that
requests access to a logical block not within the capacity of the
medium, the command is terminated with CHECK CONDITION.
This standard describes the emissions testing methods

and test limits for information technology equipment, such as
computers, office machines, or telecommunications equipment
connected to low - voltage power main networks (<600V). It does
not apply to equipment whose primary function is radio
transmission or reception as defined by the International
Telecommunications Union (ITU) Radio Regulations.
The object of the standard is to establish uniform requirements for
the conducted and radiated disturbance levels of the equipment
covered by the standard. Disturbance limits are established for
Class A and Class B equipment, and measurement methods,
operating conditions, and intepretation of results are addressed.
