11-35. The write head is centered between two
erase heads for which of the following
reasons?
1. To erase the previous data before new
data is written
2. To cancel the write current when a read
operation is performed
3. To ensure that data being written does
not spill over to adjacent tracks
4. To erase the previous data after the new
data is written
11-36. The number of tracks per inch that can be
reliably written on a disk is called the
1. linear coercivity
2. longitudinal coercivity
3. linear density
4. longitudinal density
11-37. The number of bits per inch that can be
reliably written on a track is called the
1. linear coercivity
2. longitudinal coercivity
3. linear density
4. longitudinal density
11-38. The strength of the magnetic field required
to properly record data on a magnetic
medium is referred to by which of the
following terms?
1. Coercivity
2. Oersteds
3. Density
4. Ferrous
11-39. Oersteds are used to make what type of
measurements?
11-40. A 5.25-inch floppy disk that is labeled as
DSDD has a maximum data capacity of
1. 180 kilobytes
2. 360 kilobytes
3. 720 kilobytes
4. 1.2 megabytes
11-41. The track width of a 3.5-inch floppy disk is
1. 0.l15 mm
2. 0.16 mm
3. 0.33 mm
4. 0.45 mm
11-42. Reading a 5.25-inch, 360K disk in a 1.2M
disk drive will cause what problem, if any?
1. The disk drive will read the disk with
massive read errors
2. The disk drive will be unable to read the
disk at all
3. The 360K disk will not fit into a 1.2M
disk drive
4. No problem; the disk drive will read the
disk normally
11-43. Using a 1.2M, 5.25-inch drive to write data
on a 5.25-inch, 360K disk that was originally
created in a 360K disk drive will result in
what problem, if any?
1. The 1.2M drive will not write on a 360K
disk
2. The 360K disk will not fit into a 1.2M
drive
3. The 1.2M drive will write a narrow track
through the wider track on the 360K disk,
which could result in read errors
4. None; no problem will be encountered
1. Magnetic field strength
2. Permeability of a ferrous material
3. Magnetic density
4. Magnetic polarity
