Copying entire tsv record (from file) into a single field

I would like to use copy to populate a single row in table with data
from a tsv file for further transformations.
I seem not find a way to stop copy from seeing that the tsv file does
indeed contain fields.
This my current query

        COPY raw_data
        (
        raw_record
        )
        FROM
        '/tmp/some.tsv'
        ;

Allan.
