Patent GB-1154747-A (GB)
Title: Endless Tape Cartridge
IPC: G11B23/04
Filed: 1966-06-28
Abstract: 1,154,747. Magnetic tape cassettes. LEAR JET INDUSTRIES Inc. 28 June, 1966 [28 June, 1965], No. 28995/66. Heading G5R. In a cassette containing a spool of endless tape, a temporary store 130 is provided to contain any surplus tape 135 which may extend from the spool. The cassette is similar externally to that shown in Specification 1,122,655. The rotating capstan of the co-operating player presses against the tape opposite the pinch roller 70 and causes the tape section 25<SP>1</SP> to pass the magnetic head(s) (27, not shown) and pushes the tape section 2511 towards the outer convolution of the tape on the hub 46. The tape 50 is coiled above a flange 51 and tape is fed through a gap 115, being guided by surfaces 140, 141, 105, 112. As the tape is fed into the spool housing it gradually binds against the wall 111 (50 b . . . 50g) and eventually ceases to pass through the gap 115. Tape is then caused to build up into loops, Figs. 10 to 17 (not shown), the process being aided by the tape engaging the rear surface of the pinch roller 70. When the slack tape 135 has been completely transferred to the store 130, the capstan causes the spool to rotate, and as the outer convolutions of the tape on the hub are greater than normal, tape is rewound on to the spool at a greater rate than it leaves, Figs. 18 and 19 (not shown), until the tape is operating without slack, Fig. 4 (not shown). The floor of the store 130, Fig. 7 (not shown), is raised to provide a depth of only one and a half times tape width.
