To keep the high positioning accuracy, this drive renews the
positioning compensation data during the normal operation. This drive
has two mode, Drive mode 1 and 2, for this operation.

Drive mode 1
------------
Select drive mode 1 when the function of the connected controller
satisfies following two items.

  - Read or Write operation instruction after Drive Select must be
    issued after confirming Seek Complete signal from the drive.

  - Drive Select signal must be turned off when the drive is not
    accessed even if only one drive is connected.

For this mode, the drive renews the compensation data after Drive
Select signal becomes false. During this opertion, Seek Complete
signal is false. Then the controller changes Drive Select signal to
true, and the read and write operation is executed after Seek
Complete signal becomes true.

Drive mode 2
------------
When the controller does not have the the function of Drive mode 1,
select Drive mode 2.
In ths mode, when the drive detects the renewal requirement for the
positioning compensation data, the drive stops to send data on 2/7
RD data line and waits the retry operation instruction (read retry
and recalibration) from the controller, then executes the renewal
operation at the recalibration operation. Seek Complete signal is in
false state for 1 second maximum.

The drive may be installed as figure above.
In this case, installation horizontal rate shall be within 20
degrees.

However, when inclines as the disk side comes lower side, install-
ation horizontal rate shall be within 5 degrees.

Ambient temperature
-------------------
The operating temperature range of the drive is specified at a dis-
tance of 3 cm from the drive.

The operating temperature should not exceed 45*C with considering
cooling air flow. To satisfy above condition, the base surface
temperature under the Ready condition should not exceed 60*C.

The PCA should be cooled especially with proper air circulation in
the cabinet.

Cable requirements
------------------
The total control cable length in a multi-drive connection should not
exceed 6m.
