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'
;
