Abstract
Abstract A multitrack recording apparatus includes a multi-channel recorder for recording musical timing data on a recording medium, a modulator for variably setting a recording cycle of the musical timing data, and a keyboard for designating a desired search position of the recording medium according to the musical timing data. The apparatus also includes a reproduction head for reproducing the musical timing data from the recording medium, a controller for calculating the driving position of the recording medium on the basis of the reproduced musical timing data and for controlling the driving of the recording medium to stop the recording medium at the designated search position, and a dispaly unit for displaying musical data on the basis of the reproduced musical timing data.

Claim 5
Dependent Claim
84 words
An apparatus according to claim 1, wherein the musical timing data has a sequence of numbers encoded therein, wherein the means for recording musical timing data comprises means for recording the musical timing data at periodic intervals, with one of the encoded numbers of the sequence being recorded on the medium during each periodic interval, and wherein the search position designating means comprises means for designating a desired search position of the recording medium according to a number encoded in the musical timing data.
Claim 6
Dependent Claim
217 words
A multitrack recording apparatus, comprising: a multi-channel tape recorder having a first forward speed and a second forward speed that is slower than the first forward speed; first means connected to the recorder for recording a sequence of digital data A1, A2, . . . , An at evenly spaced-apart positions on a predetermined channel of a tape, where A1 is the first data of the sequence, A2 is the second data of the sequence, and An is the nth data of the sequence, each digital data of the sequence having encoded therein a number which represents the numerical position of the respective digital data in the sequence; second means connected to the recorder for moving the tape to a predetermined digital data A i after the tape has been rewound, where 124 i≧n, the second means including means for counting digital data as the tape moves at the first forward speed, and for slowing the tape to the second forward speed when the count plus a predetermined integer is equal to i, the predetermined integer being greater than one, and means for examining the number encoded in each of a plurality of digital data as the tape moves at the second speed, and for stopping the tape when the encoded number that is examined is i.
Claim 7
Dependent Claim
217 words
A multitrack recording apparatus, comprising: a multi-channel tape recorder having a first forward speed and a second forward speed that is slower than the first forward speed; first means connected to the recorder for recording a sequence of digital data A1, A2, . . . , An at evenly spaced-apart positions on a predetermined channel of a tape, where A1 is the first data of the sequence, A2 is the second data of the sequence, and An is the nth data of the sequence, each digital data of the sequence having encoded therein a number which represents the numerical position of the respective digital data in the sequence; second means connected to the recorder for moving the tape to a predetermined digital data A i after the tape has been rewound, where 124 i≧n, the second means including means for counting digital data as the tape moves at the first forward speed, and for slowing the tape to the second forward speed when the count plus a predetermined integer is equal to i, the predetermined integer being greater than one, and means for examining the number encoded in each of a plurality of digital data as the tape moves at the second speed, and for stopping the tape when the encoded number that is examined is i.
