Hi Arpit.
Did you created the control.sql just after the backup was sucessfully executed? Ot rsome time before/later?
ORA-01200 indicates the control file contains different file sizes, waht is really present on the disks.
On the other hand, you should heck the restore, if the files were successfully restored in full size. Also check the mount options of the disks.
Compare the file sizes in backup log and restore log.

János
