Abstract: A magnetic transducer (10) formed as a composite of three different materials for reproducing and/or recording signals with a magnetic medium, the transducer including first and second generally identical sections (12, 12'), which, when bonded together in opposing relation, form a transducer having aligned recesses (13, 13') in the outer edges and a formed winding window opening (19, 19') adjacent the pole tips, the window being arranged for receiving coil turns therethrough for providing the coil (32) on a line generally parallel to the tape contact surface of the transducer (10), the core legs (18, 18') being formed of two strips of Alfesil material, or the like, deposited or sputtered on the substrate. Each core section (12, 12') is formed as a portion of an elongate ferrite block substrate (20) with a thin cap of non-magnetic material (16, 16'), initially shaped to provide opposing elongate bonding notches (26, 28) on opposite edges of a common surface (22), and an intermediate winding groove (19b) in proximate relation to one of the notches. The winding groove preferably protrudes into the non-magnetic material to about half its depth. Thereafter the workpiece is provided with an array or a plurality of equally spaced V-shaped track width defining grooves (40a-40j) oriented in a direction perpendicular to the winding groove (19b), with the grooves defining pole edges having tapered side surfaces. A chrome adhesion layer is deposited on the grooved surface and into the winding groove, followed by a core layer of suitable magnetic material, such as Alfesil material which provides a pole material covering the edges as well as the tapered side surfaces. A chrome adhesion layer is applied to the Alfesil layer, followed by a gap layer of insulating material. Two of such workpieces (20, 20') are then placed with the edges in facing opposing aligned abutting relation and glass bonding is effected by means of the two bonding notches (26, 28).

Abstract: A low cost, high speed data storage system provides word-by-word stale data detection while avoiding the need to both read and write a single memory location during a memory read operation. Two flag data storage bits are provided for each word location in addition to the normal data storage bits. As blocks of data are received by the storage system one of the two flag bits is assigned to the block on an alternating basis. Upon writing data to an address location, an assigned flag bit is written to a first state to indicate valid data. When reading, the corresponding assigned flag bit is output as a stale or invalid data signal and the nonassigned flag bit is set to a second state different from the first state in preparation for the next block of data.

Abstract translation: 低成本，高速度数据存储系统提供逐字逐行数据检测，同时避免在存储器读取操作期间读取和写入单个存储器位置的需要。 除了正常数据存储位之外，还为每个字位置提供两个标志数据存储位。 由于存储系统接收数据块，所以两个标志位之一被交替地分配给该块。 在向地址位置写入数据时，将分配的标志位写入第一状态以指示有效数据。 当读取时，相应的分配的标志位被输出为陈旧的或无效的数据信号，并且未分配的标志位被设置为与第一状态不同的第二状态以准备下一个数据块。

Abstract: Input data clock presence detection utilizes an up/down counter clocked by a reference clock, which operates at a nominal frequency rate half of the nominal rate of the input data clock, and an R/S flip-flop causing the up/down counter to count up when set, and to count down when reset. The R/S flip-flop is cleared by the reference clock and set by the input data clock. The counter is selected to count up to its maximum number and remain there when continuously clocked up. When continuously clocked down, the counter reaches its minimum number (zero) and remains there. So long as the input data clock is present and has the correct rate, after each reference clock pulse resets the flip-flop and prepares the counter to count down, there is at least one input data clock that sets the flip-flop and prepares the counter to count up. Each reference clock pulse is counted up to its maximum number indicating presence of the input data clock. In the absence of the input data clock, the R/S flip-flop remains reset, whereupon the reference clock pulses are counted down to its minimum indicating the absence of the input data clock.

Abstract: A helical tape recording and reproducing system using three longitudinally oriented tracks (172, 174, 176) that are located adjacent the helical recording area (170) where the user data is recorded (and is also digitally recorded). One of them is a physical address track (174) and it is used for recording physical address data relating to the physical layout of the tape. It contains data which identifies the size and spacing of any system zones that have been defined, as well as the volume, the format used and the absolute number of each double frame that is to be recorded or which has been recorded. Another one is a logical address track (172) that contains data relating to the content of the recorded helical tracks. Each of the logical and physical address tracks has recorded segments each of which containing data corresponding to a particular pair of helical tracks. The third longitudinal track is a servo track which contains servo information for use by the tape transport servo system to control the direction and speed of movement of the recording and reproducing system during various operations.

Abstract: A tape recording and reproducing system records blocks of user data of predetermined size by reformatting the user data blocks into physical blocks that are recorded on tape. Each physical block is recorded as a double frame on a set of successive helical tracks, preferably 32 tracks. The system has the capability of verifying whether a physical block has been accurately recorded, and if not, the system rewrites the physical block downstream without stopping or repositioning the tape. If an accuracy verification confirmation does not occur until a next physical block is being recorded, the system demarks or invalidates that physical block being written, and rewrites both the failed physical block and that following physical block dowstream of that physical block being written.
