5. Testing details
When FullCheckMicrodrive_jvc.pid is carried out, the six kinds
of testing are performed.
(1) Drive Initialization
The test checks whether the drive can recognize or not.
Errors will be detected if it cannot recognize at all as a re-
sult of fall, shock, or submersion. It is more likely to have
a failure in electrical circuit than a mechanical one (mo-
tor).
Checking items:Submersion mark, scratch on the exteri-
or, dent, and bend.
(2) Check Servo Data (DFT)
The test checks whether the disk is decentered or not.
If the motor shaft is decentered as a result of fall or
shock, the interior head cannot pick up the recorded sig-
nal on the disk.
Checking items:Scratch on the exterior, dent, and bend.
(3) Check for Scratches on Media
When a cluster error occurred, an alternative area is cre-
ated to avoid the use of the damaged cluster. This test
checks the distribution of the alternative area. It does not
detect scratches of the user data area caused by fall or
vibration.
Checking items:None
(4) Check Product Internal Error Logs
This test collects the error information that was recorded
at the time of production.
It carries two tasks, checking the Error Logs and the
numbers of the alternative sectors.
Checking items:None
(5) Check GMR Head Amplitude
This test checks the output of the head. Read and write
errors by electrostatic, by shock that changes the dis-
tance between the head and the disk may cause errors
on writing or reading.
Checking items:scratch on the exterior, dent, and bend
(6) Media Test(s)
This test checks whether the written information can be
correctly read or not by comparing writing data and read-
