K
KILOBYTE (K) – A unit of measure
consisting of 1,024 (2
10
) bytes.
L
LANDING ZONE – A position inside the
disk’s inner cylinder in a non data area
reserved as a place to rest the heads during the
time that power is off. Using this area prevents
the heads from touching the surface in data
areas upon power down, adding to the data
integrity and reliability of the disk drive.
LATENCY – The period of time during
which the read/write heads are waiting for the
data to rotate into position so that it can be
accessed. Based on a disk rotation speed of
3,662 rpm, the maximum latency time is 16.4
milliseconds, and the average latency time is
8.2 milliseconds.
LOGICAL FORMAT – The logical drive
geometry that appears to an AT system BIOS
as defined by the drive tables and stored in
CMOS. With an installation program like
Disk Manager, the drive can be redefined to
any logical parameters necessary to adapt to
the system drive tables.
LOOK AHEAD – The technique of
buffering data into cache RAM by reading
subsequent blocks in advance to anticipate the
next request for data. The look ahead
technique speeds up disk access of sequential
blocks of data.
LOW-LEVEL FORMATTING –
Formatting that creates the sectors on the
platter surfaces so the operating system can
access the required areas for generating the file
structure. Maxtor drives are shipped with the
low-level formatting already done.
LOW PROFILE – Describes drives built to
the 3 1/2-inch form factor, which are only 1
inch high.
