Abstract: Se presenta un cassette de cinta en el que los pernos guía fijos (9), (10) están ubicados en la posicion en al que se reduce el ángulo de enrollamiento (es decir, la posicion en al que el ángulo de enrollamiento del cinta no exceda de 40 degree ). Con el que la cinta magnética se embobina alrededor de los pernos guía fijos (9) (10) cuando la cinta magnética se transporta. En este cassette de cinta, la fuerza de friccion generada entre los pernos guía fijos (9) (10) y la cinta magnética (3) cuando la cinta magnética (3) se transporta, se reduce en comparacion con un cassette de cinta convencional, con lo que se reduce la carga en el motor para el transporte de la cinta magnética (3), lo que da por resultado que se prolongue la vida de la batería.

Abstract: Drawing on the observation that a signal which is magnetically recorded near the edge of a magnetic tape (12) not only projects a magnetic field that is above (and below) the plane of the tape, but also projects a field that extends away from the edge thereof, the invention calls for (tracking-) control of relative head-to-tape positioning in response to the edge-projected field of a pre-recorded edge-positioned tracking control signal (26), whereby the tightness of such control is governed directly by the spacing loss equation.

Abstract: A magnetic tape recording system which achieves very high track densities through utilization of a recording method and apparatus. A magnetic head (22) is described in which the read head gaps are parallel to but laterally offset from the write head gaps. A head assembly (24) is further provided in which the magnetic head is mounted on a rotary motor (66) for aligning the head for writing and reading tracks at different azimuth angles, as well as a stepping motor (68) and linear actuator for stepping the head between tracks. Also, a servo tracking method and apparatus (26) is presented in which writing and reading take place under servo control. This servo allows alignment of the write head gap during writing, and the read head gap during reading, through observation of low frequency servo data blocks dynamically imbedded amidst adjacent track data. The utilization of this servo minimizes tracking error due to lateral tape motion.

Abstract: A system and method of recording and playing back two different signals such as a video signal and an analogue signal representing biological data is disclosed in which a processor 14 receives the analogue signal from a patient and a video signal from a camera 10 and combines the two signals into a single stream of data. The processor 14 includes a system controller 60 which causes the analogue signal to be inserted in synchronism with the video signal into the video signal so that the analogue signals are contained in the picture information between picture frames of the video information. The single stream of data is outputted to a video recorder where the data is recorded on a convention video cassette. Upon playback the analogue signal is stripped from the combined signal and is outputted to an analogue recorder 22, 24 and the video signal is applied to a video monitor 32.

Abstract: An auto-tracking apparatus of a magnetic recording/reproducing apparatus has a circuit for discriminating whether the audio signals recorded on a magnetic tape to be reproduced were recorded by audio rotary heads or a fixed head, and a circuit for selecting outputs of the audio rotary heads in the case of the Hi-Fi recorded magnetic tape by the audio rotary heads and outputs of the video rotary heads in the case where it is determined that the magnetic tape is the normal recorded tape by the fixed head on the basis of the result of the discrimination, and performs the auto-tracking on the basis of the selected outputs. With this arrangement, the auto-tracking can be carried out irrespective of whether the magnetic tape is the normal recorded tape by the conventional fixed head or the Hi-Fi recorded tape by the rotary heads.

Abstract: An information signal delay system utilizes a solid-state memory (20) for continuously storing the information and reading it out on a time-delayed basis. An information signal is converted by a converter (14) into a digital format and compressed using conventional compression algorithms in an analyzer and converter (14). The compressed digital signal is then sequentially written into successive locations in a random access memory (20). These locations are sequentially addressed at a later point in time to read the digitized information out of the memory on a time-delayed basis relative to when it was stored in the memory. The time delay is related to the anticipated reaction time it takes to cycle completely through all of the address locations in that portion of the memory being used to store the information. The digitized information that is read out of the memory can be synthesized by a synthesizer (24) or otherwise suitably processed to reconstruct the original information signal as a delayed signal.

Abstract: A system for recording data in a stream on a recording tape in the same format that data is recorded in concentric tracks on a recording disk. The system includes a read/write transducer head for reading said tape or recording or erasing thereon; transport apparatus for transporting the tape past the transducer head to cause the head to access a stream on the tape; a first sensor for sensing a beginning-of-stream indicator on the tape; a second sensor coupled to the transport means for sensing the length of tape transported past the transducer head; a first controller coupled to the first sensor for providing an initial beginning-of-segment index pulse in response to the first sensor sensing the beginning-of-stream indicator and further coupled to the second sensor when in a formatting mode for providing end-of-segment index pulses followed by additional beginning-of-segment index pulses as a function of the length of tape transported past the transducer head following each beginning-of-segment index pulse; and a second controller coupled to the first controller for responding to each beginning-of-segment index pulse when in a formatting mode by providing a recording segment signal to the transducer head for formatting a recorded stream of segments on the tape. Each segment includes a first fill field, followed by a predetermined number of sectors including identifying addresses and data, followed by a second fill field until an end-of-segment index pulse is provided by the first controller. The segment length is equivalent to the length of a concentric track on a recording disk.
