Appeal No. 1998-2500
Application No. 08/276,154
BACKGROUND
The appellants’ invention relates to a system for reducing controller delays during
sequential data transfers in a disc drive. An understanding of the invention can be derived
from a reading of exemplary claim 1, which is reproduced below.
1. A method of controlling movement of a head over tracks on a disc in a disc drive
having a formatter for accomplishing data transfers to and from the disc and a servo
positioner for positioning the head over the disc, the method comprising:
determining a first track destination indicating a first track over which the
head is to be positioned to start a data transfer;
positioning the head over the first track with the servo positioner based
on the first track destination;
during the step of positioning, providing the formatter with a begin
transfer signal;
beginning the data transfer when the head is positioned over the first
track and in response to the begin transfer signal;
providing the servo positioner with a next track destination during the
data transfer to the first track, the next track destination indicating
a next track over which the data transfer is to take place; and
beginning positioning of the head over the next track with the servo
positioner, based on the next track destination, once the head
has reached an end of the first track.
