The surface roughnesses of its pressingly bonded surface are Rz 0.35 μm and Rmax 0.42 μm, and the surface roughnesses of its pressingly unbonded surface are Rz 0.33 μm and Rmax 0.40 μm. After so applying to the pressingly bonded surface an Ni-plating of 0.4 μm in its average thickness as to use it as a barrier metal 2, the surfaces of a wiring forming band 3 and the Ni-plating are ion-etched to subject them to an activation. Then, the activated surfaces of the wiring forming band 3 and metallic carrier band 1 are bonded pressingly to each other by rolling them at the draft of about 1%, at the speed of 10 m/min., and without any special heating.  As a result, the thin barrier layer 2 having a thickness not larger than 1 μm can be so applied to a composite material used for a transcribing method as to make possible the large cost-down of its etching process.

Title: Portable audio player and method to reduce power consumption of the player
Inventor: BIRRELL ANDREW
IPC: G10L19/00
Filed: 2000-02-10
Abstract: PROBLEM TO BE SOLVED: To realize storage of large capacity audio data while reducing electric power consumption. SOLUTION: Large amount of compressed audio data are stored in an incorporated disk 104. A portion of the data is read into a RAM 108 with low power consumption in a low access time. Then, the data stored in the RAM 108 are reproduced and the amount of data that are not reproduced is monitored. If the amount of the data that are not reproduced becomes less than a threshold value, additional data are copied into the RAM 108 from the disk 104. The time required to copy blocks of data into the RAM 108 from the disk 104 is far less than the time required to reproduce audio data having a same block size from the RAM 108. Thus, the time, when the disk 104 must be kept in an operable state, is minimized and the power consumption of a system 100 is minimized.
