摘要：

One of the popular models used to describe the operation of disk storage at high densities is the Self Consistent 2D Recording Model [3], on which many experimental results have been based [1] [2] [4]. In this paper we assume a similar model in which pulses of known shape with unknown amplitudes are jittered from a nominal regular spacing. If a disk storage device is to be compared to this model, an algorithm that will estimate the parameters of the model, given real data, has to be developed. It is also of interest to compute theoretical bounds on the accuracy of the parameter estimates for the model, so that the performance of the algorithm can be evaluated. The purpose of this paper is firstly to derive theoretical bounds on the accuracy of any estimation procedure based on this model, and secondly to describe and evaluate an algorithm that produces estimates of the model parameters with accuracy close to the theoretical bound. © 1990 IEEE
