On Coupled Dynamics of Frictional Guides in Tape Transport Systems

Stationary guides introduce friction on to a travelling tape in the longitudinal and lateral directions. The longitudinal friction increases the tape tension and the lateral friction dampens the lateral tape motion (LTM). A comprehensive mathematical model of the coupled longitudinal and lateral tape dynamics is developed. Frictional effects over a cylindrical guide are modeled as concentrated loads in both longitudinal and lateral directions. In the range of tape transport velocities that are of interest to data tape recording, it was shown that frictional damping causes reduction of resonant frequencies and resonance amplitudes. Positioning of the guiding elements could significantly influence the dynamic response of LTM.

Codd's Self-Replicating Computer

Edgar Codd's 1968 design for a self-replicating cellular automaton has never been implemented. Partly this is due to its enormous size, but we have also identified four problems with the original specification that would prevent it from working. These problems potentially cast doubt on Codd's central assertion, that the eight-state space he presents supports the existence of machines that can act as universal constructors and computers. However, all these problems were found to be correctable, and we present a complete and functioning implementation after making minor changes to the design and transition table. The body of the final machine occupies an area that is 22,254 cells wide and 55,601 cells high, composed of over 45 million nonzero cells in its unsheathed form. The data tape is 208 million cells long, and self-replication is estimated to take at least 1.7 × 1018 time steps.

Study of Generation Mechanism of Three-Body Particles in Linear Tape Recording

A major cause of magnetic spacing losses in data tape systems is pole tip recession (PTR). This study is an investigation of PTR in a linear data tape recording system and identification of the mechanisms responsible for these effects, but the results have implications for any head where the tape bearing surface is Al2O3/TiC, AlTiC. Tape cycling experiments were performed using the linear tape open system as the experimental platform with metal particle tape. All experiments were conducted within a matrix of pressure and humidity, which encompassed the system operating extremes. Atomic force microscopy was used to analyze the surface topography of the heads. Auger electron spectroscopy and x-ray photoelectron spectroscopy were employed to analyze the chemical changes on the surface of the heads and tapes. Environment was found to have a significant influence on the head/tape interface. Head wear and PTR was highest at high temperature and humidity. Water vapor was found to transform the surface layers on the TiC grains in the tape-bearing surface to TiO2. This process results in the production of TiO2 fragments that become trapped in the recessed pole tip region, acting as three-body abrasive particles. The TiO2 present on the TiC grains and on the surface of heads increases with the water content after cycling against tapes. The hypothesis is supported by the presence of Ti on the poles.

Ageing in an autobiographical context

A cohort study was carried out in 1990 in Jyväskylä, central Finland among 80-year-old residents as part of the Evergreen project. A total of 262 people born in 1910 were interviewed. In addition to epidemiological data, tape-recorded narrative stories focusing on the ageing experience were collected from a subsample of 20 people (10 men and 10 women). A five-year follow-up was carried out with the same cohort in 1995. Out of the 20 people in the original subsample, 17 (8 women and 9 men) were still alive to describe their ageing experience at 85. The analysis proceeded along the hermeneutic circle in the form of dialogue, first with the elderly narrators and then with the tape-recorded material. Unlike five years previously, most of the narrators said they had now crossed the line into old age. These findings are considered in light of the concepts of ageing, bodiliness and temporality.
