According to the present invention, in a carrying system comprising a carrying vehicle and a manufacturing apparatus the interior of which is kept cleaner than a surrounding environment, manufactured articles to be transferred are prevented from being contaminated by foreign matter or the like attached to transfer ports. The apparatus includes the use of a chemically reactive additive to remove contaminants from the wafer surface during processing. The lip portion is composed of an outside lip extending outwards and an inside lip extending inwards of the slider. An area of interest is identified where statistical uncertainty is high. A repair write command may be issued from the first memory controller port after determining that the second data does not contain any errors. The processor unit is configured to: generate a delayed digital signal; multiply a delayed digital signal by the digital signal to produce a multiplied output; and filter the multiplied output to produce a filtered output having a positive or negative sign.
