发明名称 Recording and/or reproducing apparatus for controlling the running speed of a recording tape
摘要 PCT No. PCT/JP94/00969 Sec. 371 Date Mar. 22, 1995 Sec. 102(e) Date Mar. 22, 1995 PCT Filed Jun. 15, 1994 PCT Pub. No. WO94/29858 PCT Pub. Date Dec. 22, 1994An input data rate delivered from an external device and a recording rate at the recording system for recording data onto a recording tape by using a rotary head are compared at a rate comparison section, and a comparison result is sent to a control section. The control section controls a tape running drive section for allowing the recording tape to undergo running drive. This control section carries out a switching control such that when input rate is lower than recording rate, tape running speed is caused to undergo switching control so as to shift to a lower speed side and to reduce recording rate, and when input rate is higher than recording rate at the time of tape low speed running, tape running speed is caused to be in correspondence with original stationary speed for a second time. By adjustably controlling running speed of the recording tape in accordance with input data rate in a manner as described above, effective recording can be carried out in correspondence with data rate change while the number of rotations of rotary drum and recording/reproduction frequency are maintained to be fixed. When the data rate of the input data is less than a predetermined value, the control section effects thinning of the recording operation by the recording head for a predetermined period.
