Access time on a magnetic disk is the total time taken to read or write data, which consists of seek time, rotational latency, and transfer time. For example, if a disk has a seek time of 10 milliseconds (ms), a rotational latency of 5 ms (half the time of a 60 RPM disk), and a transfer time of 2 ms to read the data, the total access time would be 10 ms + 5 ms + 2 ms = 17 ms. This calculation helps in assessing the performance of the disk for data retrieval tasks.

force that experience by ferromagnetic or paramagnetic substances when they are in the region of the magnetic field.For example, when you place a permenant magnet over an iron pin, the iron pin ( in this case, iron is ferromagnetic substances) is in the region of the magnetic field and attracted to the magnet.

Difference between define and cons is that, con is disadvantage, whereas define means to elaborate something fully.
Explain the access mechanism of a Magnetic disk. How is this access mechanism different in RAID level 5?

It's hidden behind the rear number plate, held in place with a magnetic clip. You'll need to remove the number plate and then apply a strong magnetic field to release the keyholder. Any decent hardware store will be able to provide a suitable electromagnet once you explain what it's needed for.
