your sort area size parameter may not be large enough to handle the sorts oracle needs to perform when executing the queries, so it creates a temp segment for you in the temp tablespace and then conducts the sort there. try increasing sort_area_size in your SGA and then see if the disk activity cuts down.

just before increasing the sort_area_size parameter...please perform the following action:

select sorts(disk), sorts(memory) from v$sysstat;

if sorts(disk) value > 5% sorts(memory) then this is a clear indication that you have to increase ur sort_area_size parameter in initSID.ora fine.

The database is updating the indexes on the table after DML. If it is OLTP system, too much indexes is a bad thing especially bitmap indexes.
