When a disk pack is formatted, the locations
of the tracks are controlled by which of the
following factors?
1.
2.
3.
4.
The prerecorded tracks on the servo disk
surface
The smallest increment the actuator
assembly can move the heads
An operator controlled entry of number of
tracks
A computer command designating
number of tracks per inch
When a magnetic disk set is operating
normally, what is the relationship, if any,
between the position of the heads and the
disk’s surface?
1. The heads physically contact the disk
2. The heads are held above the disk surface
by the head arm springs
3. The heads float above the surface of the
disk on a cushion of air
4. None; the position of the heads does not
affect disk operation
Which of the following procedures will help
prevent damage to the disk pack?
1.
2.
3.
4.
Store the disk pack on its side
Store the disk pack in an area where large
magnetic fields exist
Never reassemble the disk pack canister if
it is empty
Never touch the disk pack’s recording
surfaces
The term fixed hard disk system refers to
which of the following devices?
1. A hard disk system that is not broken
2. A hard disk system in which the disk is in
a sealed case and inaccessible to the user
3. A hard disk system in which the hard disk
is contained in a removable cartridge
4. A hard disk system that cannot be used
with a microcomputer

Having the thinnest magnetic media applied
to the disk platters has which of the following
advantages?
1.
2.
3.
4.
A smaller space on the disk is required to
reliably store data
The head can fly closer to the disk
A smaller magnetic field strength is
required to reliably store data
All of the above
