Abstract: VTR TAPE CASSETTE A tape cassette for use with a video tape recorder has conventional tape guiding and braking elements within its housing, including a pair of spaced guide pins for the tape adjacent each reel and a resilient strip that acts on the tape between the spaced guide pins and normally tends to deflect the tape from a straight path between the spaced guide pins for braking the tape when the cassette is not in use. A drag member is provided that contacts the tape when it is deflected to provide a tortuous path for the tape and thereby increase the resistance to tape movement.

Abstract: In a rewritable optical recording medium, a recording surface is divided into a plurality of zones by setting pitch intervals in the radial direction to be constant and a data area and a spare area for a defective sector are allocated in each zone. As for a capacity of the spare area in each zone, a predetermined total capacity of spare areas is allocated so that a spare ratio K = D1/D2 of a capacity D2 of the spare areas for a capacity D1 of the data areas becomes almost the same in the zones.
