 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 this mode, when the drive detects the renewal requirement for
 the positioning compensation data, the drive stops to send data on
 MFM 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 or 1 second maximum.

 When the drive receives Seek command before executing the retry
 operation, the drive executes the renewal operation at the recalibra-
 tion operation. Seek Complete signal is in false state for 1 second
 maximum.

      UNACCEPTABLE!                                UNACCEPTABLE!
      Never install PC board on the Top!


 The drive may be installed in a system cabinet either vertically or
 horizontally, except the horizontal position with the PCB on top and
 the vertical position on end.

 In this case, installation horizontal rate shall be within 20
 degrees.

 However, when inclines as the disk side comes lower side,
 installation 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 63*C. The PCA should be cooled especially with
 proper air circulation in the cabinet.
