In a magnetic reading/writing device, a controller derives at each radius of a recording medium a slope of a curve of track-averaged write performance with respect to an adjustment parameter, and determines a first set of fitting coefficients of a first equation approximating the derived slopes in terms of a first variable representing each radius. The controller acquires write performance dependence on a variable representing each of multiple circumferential positions of the medium by measuring track average write performance with respect to the circumferential positions, and determines a second set of fitting coefficients to approximate by a periodic function the acquired dependence in terms of the first variable. The controller corrects a condition value representing the adjustment parameter by subtracting from the condition value an adjustment value obtained from functions calculated with the first and second sets of fitting coefficients.

An image that is changed according to a change of a numerical value is displayed. A first numerical value changing section changes the numerical value between a first predetermined value and a second predetermined value. A first input value is acquired based on the numerical value obtained at a time corresponding to a time of a first operation. A second numerical value changing section changes, after the first operation, the numerical value between the numerical value obtained at the time corresponding to the time of the first operation and the second predetermined value. A second input value is acquired based on the numerical value obtained at the time corresponding to the time of the first operation and the numerical value obtained at a time corresponding to a time of a second operation. A game is controlled based on the first input value and the second input value.

A game system according to the present invention includes a server and a plurality of terminal machines; the server holds setting state information to be set in the terminal machines; the setting state information is provided to the terminal machine; and, when obtaining the setting state information, the terminal machines set the setting state information as its own local state, and executes a game based on the local state. The local states of the terminal machines vary with the situations of the game, and the local state at the moment of game end is transmitted to the server. The server which has received the local state at the moment of game end from the terminal machine updates the setting state information into the local state.

This invention provides a magnetic recording medium evaluation apparatus and evaluation method which yield results having good correlation with error rate measurements even when comparing media with different structures. Signals from a function generator are recorded in a magnetic recording medium. The recording signals are also passed through a first digital filter to obtain ideal restored signals. Reproduced signals from the magnetic recording medium are sampled in synchronization with the output from the function generator, and the discrete signals are passed through a second digital filter to obtain restored signals. The outputs from the first and second digital filters are input to an operational amplifier, and the difference between the restored signals and the ideal restored signals is taken for each sampling of the recording signals. The signal-to-noise ratio of the ideal restored signal to the average of the absolute value of this difference is used to evaluate signal quality.
