A charge-coupled device includes first-level transfer electrodes and second-level transfer electrodes alternately arranged along a transfer channel, wherein charge storage sections underlying the first-level transfer electrodes have a larger width than barrier sections underlying the second-level transfer electrodes. The first waveform equalizer equalizes a read signal, corresponding to the information read out from the storage medium, thereby outputting a first equalized signal. In some aspects and embodiments, the genetically converted yeast produce isoprenoids, preferably squalene. Each of the terminals exposed by the slot has a respective exposed portion in the slot, and each exposed portion has an equal length. 45 gigahertz and conforms to the Bluetooth standard.
