Abstract

PURPOSE:To avoid the care for error and noise, by constituting a cassette housing in an air-tight construction, in a system where laser beam is made to a minute optical spot via an optical head and the minute hole is formed on a tape for recording. CONSTITUTION:A housing 10 is formed in air-tight through molding of plastic, a tape 15 has a straight line running section 15a between guides 14a, 14b and an optical head 20 which records/reproduces the information on a tape 15 is provided at a front wall 10c along the section 15a. The optical head 20 records the information on the tape 15 with laser beam (optical beam) from an external device or reads in the information. Since the tape 15 is contained in an air-tight housing 10, no dirt and defect is given on the tape to achieve a high density recording.
