It's not the join that's different, you need to use group by clause and group_concat() function to produce the expected results in the record field of the output. Whether it is a left or inner join between the 2 tables, that's for you to decide. Based on the sample data an inner join will work just fine:

SELECT a.id_tag, a.Name, group_concat(b.Record) as record
FROM table1 a INNER JOIN table2 b ON a.id_tag = b.id_tag
group by a.id_tag, a.Name
