Which of the following materials is used to make magnetic tape?
The base material of magnetic tape is made with what material?
Which of the following can happen if the magnetic particles used to make magnetic tape aren’t uniform in size?
The tape’s surface will be abrasive which reduces the magnetic head’s life
Generally, short magnetic oxide particles are used on magnetic tape to record lowfrequency signals and long particles are used to record high-frequency signals.
Why does digital magnetic tape use a base material about 50 percent thicker than analog magnetic tape?
Thicker tape allows the tape to withstand the more strenuous starts and stops
There are four types of tape errors that can degrade the performance of a magnetic recording system. Which of the following tape errors is the most common and causes a 50% or more drop in signal strength
Which of the following contaminants can cause signal dropouts?
Which of the following items on magnetic tape will cause noise errors?
Magnetic tape can eventually become unusable when it comes in contact with the fixed surfaces of a recorder over long periods of time. What causes this type of tape failure?
Ideally, magnetic tape should be used and stored within what temperature and humidity range?
60 - 80º F, 40 - 60% humidity
Using magnetic tape in a workplace that exceeds the ideal temperature and humidity ranges can cause which of the following types of environmental damage to the tape?
At temperatures above 130 degrees, what happens to a tape's oxide coating?
What causes head-to-tape sticking?
The tape binder glue softens
Which of the following environmental conditions could create static electricity which attracts dirt build-up on the tape and tape recorder parts?
Relative humidity of 5%
Excessive tape and head wear caused by increased friction as the tape passes over the heads can happen if the relative humidity is more that what maximum percent?
Winding errors can happen when improper winding practices create an excessive or uneven force as the tape is being wound onto a tape reel.
When winding a tape onto a reel, you notice that a sudden stop causes the outer layers of the tape to continue to spin after the inner layers have stopped. What type of deformed tape pack does this cause?
The magnetic tape on your reel is unwinding unevenly and rubbing against the sides of the reel and the recorder’s tape guides. What type of deformed tape pack could cause this condition?
Which of the following tape pack deformities is an example of windowing?
The tape pack contains voids or see through air gaps
Which of the following materials can be used to make tape reels?
The flanges of a magnetic tape reel are designed to guide the magnetic tape onto the reel.
Magnetic tape is erased by exposing it to what type of magnetic field?
A gradually decreasing ac field
Which of the following is a disadvantage of using a tape recorder’s erase head to erase magnetic tape?
It’s slow and It may not do a complete erasure
Which of the following is NOT an appropriate place to keep a magnetic tape reel or cartridge?
Stored in a plastic bag
Laying on top of a magnetic tape recorder
Which of the following is a CORRECT method for handling magnetic tape?
Never handle or touch a tape’s working surface
Which of the following is a CORRECT method for storing magnetic tape?
Store tapes away from equipment that generates stray magnetic fields
