The Access/seek times test measures the access or seek times of optical drives for discs inserted in the drive in three partial measurements. The results of all three partial measurements are displayed in the Access times area, to the right of the graph.
Before starting the test, you can use the options to define whether you want to test the access time or the seek time, as well as how many times you want to run the test.
The following partial measurements are performed for seek or access times:
|
Random
|
Moves the read head to a random position on the disc.
|
|
1/3
|
Moves the read head from the start of the disc over the first third.
|
|
Full
|
Moves the read head from the start of the disc to its logical end, i.e. to the outermost position where data is saved on the disc.

The access time is the time a drive needs to move the read head to a specific position on the disc that is inserted in the drive and to additionally read an area of the disc. In other words, the access time encompasses the seek time and in addition the period of time for reading a specific area.
| Search Time |
The seek time is the time the drive needs to move the read head to a specific position on the disc that is inserted in the drive. In other words, the seek time encompasses the period of time between the arrival of a write or read command and commencement of the actual write or read process.
