1. A Data Storage Device (DSD), comprising:
- a disk for storing data, the disk including a data object zone for storing data objects;
a volatile memory for storing data;
a head for writing data on the disk; and
a controller configured to;
control the head to write a most recent version of a data object from the volatile memory onto the disk in the data object zone; and
control the head to rewrite at least one most recent version of a previously written data object in the data object zone so that an earlier version of the data object written from the volatile memory does not interrupt a contiguous plurality of most recent versions of data objects stored in the data object zone.

Abstract
Managing data objects in a Data Storage Device (DSD) including a disk and a volatile memory for storing data. A data object is written from the volatile memory in a data object zone of the disk of the DSD. At least one most recent version of a previously written data object is rewritten in the data object zone so that an earlier version of the data object written from the volatile memory does not interrupt a contiguous plurality of most recent versions of data objects stored in the data object zone.

14. A method for managing data objects in a Data Storage Device (DSD) including a disk and a volatile memory for storing data, the method comprising:
-
writing a data object from the volatile memory in a data object zone of the disk of the DSD; and rewriting at least one most recent version of a previously written data object in the data object zone so that an earlier version of the data object written from the volatile memory does not interrupt a contiguous plurality of most recent versions of data objects stored in the data object zone. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
